Target Monterey (12.0) as the minimum compatible os for arm64 wheels
The tf-nightly-macos wheels are currently being tagged with "11_0" so this PR changes the CI to target Monterey (12.0) to be the minimum compatible OS to be consistent with how we released the Apple Silicon wheels for TF 2.13. 

Also, removed redundant configs.
