Support configuration with PHP 8 attributes through AttributeDriver (#8)

This registers the new `AttributeDriver` added in
https://github.com/webfactory/object-routing/releases/tag/1.7.0.

In the next major version, we can then remove the `AnnotationDriver` and
get rid of the `annotation_reader` service dependency.
