We've decided to use `2.2.0-snapshot.20220504.9851.0.4c8e027d` as the RC
for 2.2, so let's make sure we don't produce another, confusing 2.2
snapshot after it.
At this point, should we find something wrong with
`2.2.0-snapshot.20220504.9851.0.4c8e027d`, we should fork off it and
start a 2.2.x branch.

The release process for 2.1.0 is ongoing. I think it's safe to say at
this point if we need to change the RC we'll do it with backports.
