VarDumper component already supports PHP 8.1 enums, but it didn't have tests.

enum UnitEnumFixture {
    case Hearts;
    case Diamonds;
    case Clubs;
    case Spades;
}

dump(UnitEnumFixture::Hearts);
```
```
Symfony\Component\VarDumper\Tests\Fixtures\UnitEnumFixture {#435
  +name: "Hearts"
}
```

```php
enum BackedEnumFixture: string {
    case Hearts = 'H';
    case Diamonds = 'D';
    case Clubs = 'C';
    case Spades = 'S';
}

dump(BackedEnumFixture::Hearts);
```
```
Symfony\Component\VarDumper\Tests\Fixtures\BackedEnumFixture {#157
  +name: "Hearts"
  +value: "H"
