[minor] Migrate to pyproject.toml

[liamhuber]

And use this as a testing ground for improvements to the centralized CI.

• Local env is now fully pinned; we'll rely on the release action to dynamically relax these
• The new ability to test on more versions of python is exploited -- 3.12 is working fine
• The new ability to test an alternate environment is used to test some older versions, allowing us to expand the pypi lower limit bounds
  • Here the renaming script is working fine, but I'm using this repo as a place to test the full release cycle, as I still haven't figured out a good and perfectly safe way to test releases (which may not exist), or even better routines for mocking them (which certainly do)
