On Symfony <= 6.2 serializer versions the supportsDenormalization was always called in \Symfony\Component\Serializer\Serializer::getDenormalizer.

When the getSupportedTypes logic was introduced for Symfony 6.3 serializer some if statement conditions were introduced and if they are true the supportsDenormalization logic is not called at all anymore. Those conditions currently prevent a legit use-case that worked prior to 6.3 from calling the supportsDenormalization method - the case being when the denormalizer is supposed to denormalize a collection/array of objects. This use-case still works even on the 6.3 serializer as long as the denormalizer does not implement the new getSupportedTypes method, but that is triggering a deprecation.

This PR aims to fix that so that denormalizing an array of objects still works even when using the new getSupportedTypes method in a denormalizer.
