desired version: 20220623.0

I was going to create a PR to update Abseil, but then I found that there are two versions of the package, so I don't know what I am supposed to do.

The version 20211102.0 was added by @jonringer in a0da54e.

Also, it looks that an update to abseil-cpp needs to target staging?
