Deprecated configuration key for serializer

[mrskhris]

Page https://api-platform.com/docs/core/serialization/#configuration-for-symfony mentions setting the following parameter:

# api/config/packages/framework.yaml
framework:
serializer: { enable_annotations: true }

It appears this parameter has been deprecated and later removed in 7.0:
https://github.com/symfony/framework-bundle/blob/7.2/CHANGELOG.md#70

Remove the framework.serializer.enable_annotations config option, use framework.serializer.enable_attributes instead
