We are running the unit tests on macOS 12,13,14 and Ubuntu 22 for python versions 3.11 and 3.12
Do we need all these different macOS types? Should we instead test on lower python versions to see potential errors

Removed MacOS 12 and 13 from the buildbot.

It looks like MacOS 13 is still under development so we should try to add that test back into the mix.

The next most common lower version of python is 3.9. But if pydantic requires 3.11, then that sets the floor for where we can test.
