Code monitors: remove `repo:` filter requirement for code monitor queries
Created by: camdencheek
Closes #31943 (closed) Closes #31941 (closed)
This removes the repo: filter requirement for code monitors everywhere except on sourcegraph.com. I think it's best to keep in place on sourcegraph.com because it's a bit too easy to accidentally create a code monitor that hits every repo on sourcegraph.com, which will cause unnecessary load.
Test plan
Tested behavior with sg start and sg start dotcom
