* Replace pkg_resources with importlib_metadata

Fixes #10964. The other reason for this change is that pkg_resources has been [deprecated](https://github.com/pypa/setuptools/commit/8fe85c22cee7fde5e6af571b30f864bad156a010

) in favor of importlib_metadata.

* Reduce to a single importlib_metadata import switch

* Trigger CI
