This synchronizes the metadata driver setup with changes in the core library, accounting for:

• Only add the YamlDriver to the chain when symfony/yaml is installed serializer#1497 (only register the YAML driver when symfony/yaml is installed
• Don't return a metadata object unless there is explicit annotation or attribute configuration serializer#1494 (the big internals cleanup)
• [B/C Break] Make the Annotations package optional in the builder API serializer#1471 and Symfony deprecations which will remove Annotations support in 7.0

I guess that this needs a new tag in the serializer library and it should require only that in the composer.json, right?

The bump on the metadata package isn't strictly needed, but the serializer package has this as its minimum so figured I'd change it to match.
