ci: Use 'macos-13' runs-on to continue using x86 based macOS runners

[matthewfeickert]

• The 'macos-latest' runs-on option has been changed to be the Apple silicon based 'macos-14' runners. To continue to use the x86 based macOS runners use 'macos-13' instead.
• This is needed as the current libomp install procedure is only valid for x86.

Doesn't address Issue https://github.com/thaler-lab/Wasserstein/issues/15, so Windows build will fail.

@j-s-ashley @rikab This is ready for review. This implements a guard that @henryiii added to Scikit-HEP projects a while back until people added Apple silicon support explicitly.

FYI, you can disable the cancellation of running jobs if there's an error:

strategy:
  fast-fail: false
  matrix:

Yeah, I usually leave fail-fast as true as to not just let all my linux jobs run on and on.
