[v2] Add support for Python 3.13

[hssyoo]

Adds support for Python 3.13 and updates the bundled Python interpreter in installers to 3.13.2.

• Due to dependency conflicts, Python 3.8 support needs to be dropped.
• Upgrade ruamel.yaml.clib to 0.2.12 for Python 3.13 support.
  • Wheels aren't available for macOS < 14 on x86. Opened a ticket here, but it should be fine to require source install since macOS comes with C compilers: https://sourceforge.net/p/ruamel-yaml-clib/tickets/43/
• Remove explicit dependency on zipp since the latest version supports Python 3.9+.
• Some packages installed from source will have their site packages directories replace . with _. This causes some dependency tests to fail because it'll make an assertion like assert ruamel.yaml.clib == ruamel_yaml_clib. If it fails, we normalize the package name and try 1 more time.
• Python 3.13 no longer considers / an absolute path in Windows, which is what os.path.sep returns. For tests, we wrap it in os.path.abspath, converting it to C://.
  • https://docs.python.org/3/whatsnew/3.13.html

  • On Windows, isabs() no longer considers paths starting with exactly one slash (\ or /) to be absolute. (Contributed by Barney Gale and Jon Foster in gh-44626.)
