add ventura and arm64 test targets, remove big sur

This reworks the macOS github actions to target Apple silicon for tests.
To simplify the test matrix, removing big sur and adding ventura.
Also some cleanups to the test script. We really don't need the 'x'
workaround for non-POSIX shells, and it got confusing writing "xx86_64".
