Get macos-12+, including osx-arm64 (i.e. macos-latest) runners working in CI

Follow-up from #841 (review)

[IAlibay]

Overview of issue

• macos-13 (x86_64) is not compatible with the current conda-forge deployments of AT22 or AT23. The wheels will get picked up and installed, but SQM will fail
• macos-14 (osx-arm64) does not have compatible AmberTools wheels

This has either been addressed or moved to other issues.

The lack of compatibility between AT and macos-13 is an issue that will need a look at.

@mikemhenry do you know if any recent ambertools builds are compatible with macos-13? If not, we will drop our support of macos-13 as well.

That is a good question, recent versions no, but older versions yes? I think the easiest way to check is to see if an env will solve os macos-13 with ambertools 22, 23, or 24. You might need to check python versions 3.9-3.12, since there might be a sweet spot where it all algins.

@mikemhenry the issue isn't so much that it doesn't resolve but that there's an issue with the binary - i.e. if you run SQM it'll fail horribly.
