Subject

Add support for "jms/serializer-bundle" 4.x.

I am targeting this branch, because this change respects BC.

Changelog

### Added
- Support for "jms/serializer-bundle" 4.x.

To do

• Wait for a release of "friendsofsymfony/rest-bundle" including Use symfony decoration for jms serializer handler registry FriendsOfSymfony/FOSRestBundle#2319.

Not sure we need to give this support. The jms serializer is removed on 4.x and the feature that uses this library is deprecated already.

Not sure we need to give this support. The jms serializer is removed on 4.x and the feature that uses this library is deprecated already.

The motivation for this change is not the feature provided in this package, but the blocker this dependency generates for 3rd party projects:

composer why-not jms/serializer-bundle ^4
sonata-project/media-bundle  3.35.1      requires  jms/serializer-bundle (^2.3.1 || ^3.0)
