Add support for Python 3.12

[matthewfeickert]

pkg_resources is deprecated and removed in Python 3.12:

Python 3.12 has removed pkg_resources from the standard library (moved to setuptools): https://docs.python.org/3/whatsnew/3.12.html

setuptools docs: Package Discovery and Resource Access using pkg_resources

Use of pkg_resources is deprecated in favor of importlib.resources, importlib.metadata and their backports (importlib_resources, importlib_metadata). Some useful APIs are also provided by packaging (e.g. requirements and version parsing). Users should refrain from new usage of pkg_resources and should work to port to importlib-based solutions.

Currently (ebc66fd54778e13409a0966004e6d4266f79f8d0) used in src/recastatlas/config.py, src/recastatlas/subcommands/catalogue.py, and src/recastatlas/subcommands/auth.py, and so needs to be removed.

At the moment recast-atlas is only testing and supporting up to Python 3.11:

PRs like https://github.com/recast-hep/recast-atlas/pull/139 also need to get fixed in all of the yadage ecosystem too before a Python 3.12 compliant recast-atlas can be made.
