Search before asking

• I searched in the issues and found nothing similar.

Motivation

We recently upgrades the docker images produced for 2.11, 3.0, and master branches to Ubuntu 22.04, but we left all of the github workflows using ubuntu 20.04.

Solution

s/20.04/22.04/g in .github directory in each of branch-2.11, branch-3.0, and master.

Alternatives

Reverting to ubuntu 20.04.

Anything else?
