**Description of PR**
https://github.com/actions/setup-python/issues/852
With macos-latest moving from macos-12 to macos-14, there are fewer
available python versions.

This PR pins the previous macos-latest runner to macos-12 and adds
entries for python 3.11 and 3.12 available on macos-14.

Also, it looks like the required status checks need to be updated.
