The #33573 modified Symfony's form themes. But the [FormType](https://github.com/symfony/form/blob/master/Extension/Core/Type/FormType.php) don't allow the option `row_attr` so the OptionResolver throw an exception that the option is unknown.

This PR basically add the option and give it to the form view (like `label_attr` do)
