Next to #39804, this PR adds a new `#[TaggedItem]` attribute that ppl can use to define the index of their service classes when they're used in tagged collections (iterators/locators.

This replaces the `public static getDefaultName()` and `getDefaultPriority()` methods that ppl could use for this purpose:
```php
#[TaggedItem(index: 'api.logger', priority: 123)]
class MyApiLogger implements LoggerInterface
{
}
```

This will ship the corresponding service at index `api.logger`, priority=123 when building locators/iterators.

Hello,

we have a project where we work with background colors on links. When we define this in our stylesheet, the Web Profiler picks these styles up due to the cascade. We added two CSS statements to the Web Profiler stylesheet to be explicit about the transparent background.

AWS S3 signature is not supported anymore, which mean the old "raw HTTP" implementation does not work anymore, and only the implementation that use "async-aws" works.

This PR move "async-aws" to the "requires" section in order to fix that.

This adds a `Validator::createValidCallable()` (I'm very open for other name suggestions) that returns a boolean instead of exceptions. This allows usingit in places where booleans are expected, for instance in the referenced OptionsResolver case:

```php
$resolver->setAllowedValues('name', Validation::createValidCallable(
    new Assert\Length(['min' => 10 ])
));
```

Hello, this is my first contribution to Symfony Framework. It's time to pull my weight.
About the issue:
I did improve an error message to include passed argument's name and the latest optional argument's name.

An author also mentioned "But which command?", however this is shown twice as we can see on the screenshot above so I skipped that.

#37265 was created as a fix for #37100. However, when #37327 was merged, the original bug was also fixed with a different solution (allowing null values on `InputBag::set`) and parts of #37265 are not needed anymore. By using only `InputBag` as the `$request` bag we can tighten the typehint again and make static analysis a bit more useful.

Check if templating engine supports given view

Currently the `ControllerTrait::render` and `ControllerTrait::renderView` methods assume that when the `templating` service is available it can always render the given view via that service.

However, that might not be the case. For example if `framework.templating` is not configured to support the `twig` engine for example but only some other custom engine, e.g.

```yaml
framework:
  templating:
    engines:
      - foobar
```

it will fail when the given view references a Twig template for instance and the configured engine cannot render that.

The `Symfony\Component\Templating\EngineInterface` which `templating` implements defines a `support` method:

2536e178b1/src/Symfony/Component/Templating/EngineInterface.php (L56-L63)

which should be used here, in order to make sure that `templating` actually does support rendering the given view.

| Doc PR        | https://github.com/symfony/symfony-docs/pull/14731

There are at least 3 ways to get the container in a test class:

```php
class FooTest extends WebTestCase
{
    public function testGetContainerA()
    {
        $kernel = self::bootKernel();
        $container = $kernel->getContainer();
    }

    public function testGetContainerB()
    {
        self::bootKernel();
        $container = self::$container;
    }

    public function testGetContainerC()
    {
        $client = self::createClient();
        $container = $client->getContainer();
    }
}
```

I suggest to add a fourth =)

Basically, in tests you should always use the `test.service_container`. It is hard to remove A and C, but I can deprecate C and add a helper function.

```php
class FooTest extends WebTestCase
{
    public function testGetContainerTheOnlyWayYouShouldUse()
    {
        $container = $this->getContainer();
    }
}
```

This new way will also boot your kernel if it is not already booted.

The `AnnotationsCacheWarmer` is creating a cached a `new CachedReader` in the `doWarmUp()`. But this will fail if doctrine/cache is not installed. In #40338 I added the `kernel.cache_warmer` tag on `annotations.cache_warmer` service even though the doctrine/cache is not installed.

This PR will make sure `AnnotationsCacheWarmer` is using the `PsrCacheReader` when available.

This bug was not found in the tests because doctrine/cache is always installed.

Big golden star to @jrushlow because you test dev-master.

Closes https://github.com/symfony/symfony/issues/37879

`NotificationEmail` can be created public from the `asPublicEmail` method in any context but with the Notifier component. In this case it is created by it as not public and therefore displays the importance in the subject of the email.
For end users, aka not admin, the importance in the subject's email is not necessary.
This PR will allow if needed to set a `NotificationEmail` as public even after being created, wherever it was created.

I am not sure how to handle the version in the changelog.
For the tests I don't know what's the policy so I just added a new case in each test case.

minor #40428 [Console] Fix type of InputOption::$default (oliverklee)
This PR was merged into the 4.4 branch.

[Console] Fix type of InputOption::$default

Options can also be `int`s. So add this type to the PHPDoc parameter
type annotation of `InputInterface::setOption` and the return type
annotation of `InputInterface::getOption`.

When context contains a closure, it can't be serialized. In that case, we now assume that fingerprint is always different, and in that case, email will always be re-rendered

3a2d1b4a0a bug #40427 [Console] Stop accepting ints as InputOption defaults
The types accepted and provided by `InputInterface::getOption`
and `setOption` do not include `int` (and passing something like
`--option=123` will set the option to the string `"123"`, not
to the integer `123`).

The `InputOption` default types should match this.

Fix `ConstraintViolation#getMessageTemplate()` to always return `string`

`ConstraintViolation#getMessageTemplate()`'s inherited signature states that `string` is
to be returned by it at all times, yet the implementation returns `null` when no message
template had been provided at instantiation.

This patch obviates it, returning an empty string when the
message template is `null`.
