Subject: [PATCH] Pin CI jobs to Ubuntu 20.04 (#7359)

The release job was pinned to Ubuntu 20.04 to avoid glibc breakage in
https://github.com/nushell/nushell/pull/7290. This PR updates the CI
jobs to keep things consistent (it would sure be unpleasant if things
worked in CI but not at release time).
