Is `doctrine/annotations` still required?

We should test (later) if this is still necessary.

It is probably still necessary: #613 (comment)

Maybe using attributes instead of annotations could avoid this issue and remove this optional dependency. But I don’t use @QueryCounter so I won’t try to update it.

Error with Symfony ^5.4 and ^6.4:

The annotationReader is not available

Symfony ^7.0 has no issue.

Since their end of lifes are for 2029 and 2027, and we try to keep compatibility with old versions because people often more time to upgrade, we should be able to remove doctrine/annotations in 2030.
