Remove Docs Team as CODEOWNERS (#2753)

Removes Docs as CODEOWNERS from the repo. As part of a project to reduce courtesy reviews, the Docs Team is limiting CODEOWNERS entries to repos that single-source content into the docs site or where our review is critical. We’re still happy to review content if you reach out to us directly.
