ENH: Update ApplyScriptToRemotes.sh for Github auth token protocol

Fixes:
- Fetch repo with https instead of git protocol
- Push repo with git username and auth token instead of
  username/password combination

Quality updates:
- Allow switch into already-existing branch to mitigate rerun effort
- Confirm remote path before each push to minimize accidental push
  to wrong remote
