chore: upgrade macos-12 to macos-latest-large in workflow

The macOS 12 Actions runner image began deprecation on 7/10/24 and will be fully unsupported by 3/12/24 for GitHub and ADO. For more details, see actions/runner-images#10721.

Using macos-latest-large instead of macos-latest, as the latter is ARM-based, while we require AMD architecture (abbbc87). For more details, see actions/runner-images#9741, and the table in https://github.com/actions/runner-images/blob/ubuntu24/20241117.1/README.md#available-images.
