Bump Github VM MacOS-13 -> MacOS-14

[scott-huberty]

Reference issue (if any)

closes #13388

What does this implement/fix?

Now our tests will run against MacOS Sonoma and MacOS Sequoia, both on apple silicone architectures. I selected MacOS-14 based on the listed available runners here

Additional information

Github, Python (I think), and Apple itself are deprecating support for Intel Macs.

Marking for merge-when-green, thanks in advance @scott-huberty !

Will require an adjustment to our merge protection rules, which I'll make after the CIs come back green

@scott-huberty I wasn't sure why Windows was timing out here. Comparing the GHA logs between the runs here and one that was green a couple of days ago I couldn't find any meaningful differences. I realized we might as well test Python 3.11 and 3.12 somewhere anyway, so I bumped a couple of jobs up from the min 3.10. It looks like it's working. I'm guessing there have been some changes to the conda packages for 3.10 that cause the solver to have issues, and changing the Python version magically fixes things. This sort of thing can happen with conda sometimes 😢

Anyway, hopefully this will land today 🤞 No action needed from your end

Makes sense - thanks!
