Upgrade GitHub Actions macOS runners to 13 and 14 (and possibly 15)

[georgetayqy]

What feature(s) would you like to see in RepoSense

The current macOS 12 GitHub Actions runner is being deprecated and should not be used in our existing workflows. For more information, see here.

Let's upgrade our existing GitHub Actions workflow to use the macOS 13, 14 and possibly 15 images for better compatibility with our CI actions.

Is the feature request related to a problem?

Existing CI workflows will not execute the checks for macOS 12, appearing as an error or a job cancelled event on GitHub.

See #2232 for an example of such a failed workflow.
