[RETROACTIVE] Git repositories SSH remote identification changed

Between 12:39 UTC and 20:10 UTC, some users may have experienced an error message WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! when pushing code using git+ssh on our Git repositories. This was due to an update of the allowed signature algorithms of our SSH servers. Users that had an old signature algorithm stored in their known_hosts ssh file were impacted.

The change has been rolled back.
