Subject: [PATCH] Run tests with multiple Python versions

Run the CI tests with both the earliest supported Python version and
the latest stable release.

The intent is to quickly notice when new features require adjusting
the oldest supported Python version and also detect when the latest
stable version breaks old code (as when 3.12 removed `imp` and we
switched to `importlib` in #311).
