## Summary of the Pull Request

CONTRIBUTING.md currently has documentation suggesting to file a 'Community Guidance Request' if a user doesn't know how to do something.  This issue was identified by @hessedoneen in #9765 .  Per @zadjii-msft  this option has never really existed, and should be struck from CONTRIBUTING.md .  This PR does just that.
