Symfony version(s) affected: 5.3.0-RC1

Description
When enabling auto_mapping validation, crash appear when validating an entity with a json-type attribute (e.g. roles attribute of an User entity)

How to reproduce
1/ Enable auto_mapping validation

framework:
    auto_mapping:
      App\Entity\: [ ]

2/Create an entity with a 'json' type (with make:user for example)

/**
 * @ORM\Entity(repositoryClass=UserRepository::class)
 */
class User implements UserInterface, PasswordAuthenticatedUserInterface
{
//...
    /**
     * @ORM\Column(type="json")
     */
    private array $roles = [];

//...

3/ Validate an instance of this entity in any way. It will results in a Warning: Undefined array key 0 error.

Possible Solution
I think it is due to the recent changes made in Symfony\Component\PropertyInfo\Type class (MR #39020). getCollectionValueTypes() is now used instead of getCollectionValueType() in Symfony\Component\Validator\Mapping\Loader\PropertyInfoLoader#loadClassMetadata() method.
There is a type mismatching in a condition now :

// Symfony\Component\Validator\Mapping\Loader\PropertyInfoLoader.php (line 120)
            if (!$hasTypeConstraint) {
                if (1 === \count($builtinTypes)) {
                    if ($types[0]->isCollection() && (null !== $collectionValueType = $types[0]->getCollectionValueTypes())) {
                        [$collectionValueType] = $collectionValueType;
                        $this->handleAllConstraint($property, $allConstraint, $collectionValueType, $metadata);
                    }

                    $metadata->addPropertyConstraint($property, $this->getTypeConstraint($builtinTypes[0], $types[0]));
                } elseif ($scalar) {
                    $metadata->addPropertyConstraint($property, new Type(['type' => 'scalar']));
                }
            }

I think condition (null !== $collectionValueType = $types[0]->getCollectionValueTypes())) should be changed to ([] !== $collectionValueType = $types[0]->getCollectionValueTypes())) because getCollectionValueTypes() returns only array.
At least, this solution fixes my problem but I am not aware of other getCollectionValueTypes() usages and they should be verified because this new method is slightly different than the older one (getCollectionValueType()).
