commit 5a97b7f4345a09fcf85af6e742ffb33cf286a358
Author: Victor Tong <vitong@microsoft.com>
Date:   Mon Oct 11 17:40:49 2021 -0700

    This fix fixes the scenario when we try to make a Git commit even though there are no changes in the .github directory. Instead of running git add .github/ and git commit we first check to see if there are changes in the .github directory
