chore: use the macOS 14 with M1 processor runner on workflows (#522)

### Summary

We were using an older version of macOS (macOS 12). As of January 30th,
2024, GitHub announced the new M1 macOS runner. [Here's the link for the
blog
post](https://github.blog/changelog/2024-01-30-github-actions-introducing-the-new-m1-macos-runner-available-to-open-source/)

### Test plan

We need to make sure CI passes with the changes
