Community Wishlist Survey 2022/Create "on hold" status for wiki requests

Proposed by Raidarr (via Miraheze Meeting)|Raidarr (via Miraheze Meeting)]]

Proposal summary: Add "on hold" status for handling wiki requests.

Full proposal: Allow wiki creators to place wiki requests on hold pending their response to questions or pending the review of another wiki creator for a second opinion. There should also be the ability to lock wiki requests when placed on hold to prevent another wiki creator from erroneously approving/declining. (The lock should be able to be removed with the click of a button by any wiki creator; the "lock" should only serve as a visual indicator that the request is being looked at.)
