upgrade macos version in actions

[vitahlin]

GitHub has deprecated older macOS runners, and macos-13 is no longer supported.

1. The latest version of cross-platform-actions/action does allow running on ubuntu-latest (Linux runner) and does not strictly require macOS.
2. Previously, cross-platform-actions/[email protected] used runs-on: macos-13. I checked the latest version of cross-platform-actions, and the official examples now use runs-on: ubuntu. I think we can switch from macOS to Ubuntu.

can we pin the SHA instead?

OK, use SHA of version 0.30.0 instead
