GitHub Actions have moved the macos-latest runners over to macOS 14 ARM64.
This PR updates our macOS CI script to user these ARM-based macOS runners. Specifically it drops Python 3.8 and 3.9 from the Mac tests (as these are no longer supported) and switches over to the new homebrew prefix (/opt/homebrew/) used on the ARM-based Macs.
