Make Catanatron Python 3.12 Ready

[bcollazo]

It seems "distutils package is removed in python version 3.12" and Catanatron depended on that.

See: https://stackoverflow.com/questions/69919970/no-module-named-distutils-util-but-distutils-installed, https://docs.python.org/3.12/whatsnew/3.12.html, and https://peps.python.org/pep-0632/#migration-advice for more information.

Right now it seems users that use 3.12 from the get-go get errors like:

    import distutils.core
ModuleNotFoundError: No module named 'distutils'

It'd be nice to include these in the CI/CD as well.

Hmm, I don't see a reference to distutils in the catanatron code; more than likely, one or more of the deps needs to be upgraded to support 3.12.

Somewhat related, I see this paperspace Dockerfile pointing to 3.8. Should this ticket include updating that Dockerfile? Or is it not used and can be deleted?

Got it, makes sense. For now, we can keep around the Paperspace Dockerfile around even if with an old version of Python in case someone wants to GPU train in the cloud. Let's leave this ticket to just ensure the main instructions on the readme / installing the catanatron-play CLI in a Python 3.12 virtual environment works like a charm.
