`mt-sync-code-data.yml` should also run on pulls request but automatically skip downloading new data and app release

Change `shared-overwrite/.github/workflows/mt-sync-code-data.yml`
Add trigger for pull requests changes.
All steps requiring `github.event.inputs.skip-download-data == 'false'` should be skipped if pull request
All steps requiring `github.event.inputs.skip-app-release != 'true'` should be skipped if pull request.
