Summary: Ref T11114. Obsoleted by Modular Transactions + EditEngine + CommitMessageField + we just "hard code" the title of revisions into the page because we're craaazy.

Test Plan:
  - Made an edit on `stable`.
  - Viewed the edit on this change, it still had the proper UI strings.
  - Edited/created/updated revisions.
