Run mac/x86 tests on macos-13 runners

[masklinn]

Python 3.11 and above are universal architecture binaries and can be forced via arch, but the non-universal binaries don't run on m1: https://github.com/masklinn/ci-test/actions/runs/11296863554

So currently the wheels workflow is not testing on x86 at all... which I guess is explicit anyway since I'm explicitly only testing on x86 for windows and linux and aarch64 on mac? Would be a good idea to test every wheel...

arm64 linux (and windows) runners are not currently in preview so this would have limited utility. Work on this should probably wait for actions/runner-images#10820 then the entire matrix can be implemented properly.
