Python 3.12 Compatibility

[AndydeCleyre]

I thought it would be worthwhile to have an issue tracking anything needed for Python 3.12 compatibility, as more blockers may come up as some are fixed. So far I can identify two problems:

• AttributeError: 'FileFinder' object has no attribute 'find_module' when running on python 3.12 #372
• distutils is no longer in stdlib

EDIT: Both of these are now addressed by PR #373.

For the distutils migration, it may be as simple as:

diff --git a/ward/_collect.py b/ward/_collect.py
index d72a57e..d288b10 100644

Python 3.12 was released on October 2nd.

@darrenburns I'm not sure how much availability you have for ward maintenance these days, or if there's someone else you can bring in to help, but I'd love to keep using this project with the current Python release and going forward.
