CI: pin to Ubuntu 20.04. (#5407) (#5418)

CI is currently broken because `ubuntu-latest` moved to 22.04, which is missing at least one package (`libclang1-9` used in our CI jobs) and may be causing other issues as well. This PR pins us back to 20.04; separately we should look into upgrading when issues are resolved. Co-authored-by: Chris Fallin <[email protected]>
