Update UBUNTU_VERSION to 22.04 LTS (or provide multiple versions)
Description
I'm using the gitlab-runner:ubuntu container image as the base for a runner container with sysbox. This setup seems to require a newer version of the go compiler now, which is not included in focal anymore.
Proposal
It would be useful to have either a separate jammy based ubuntu image or for the current ubuntu image to be updated to the latest LTS release.
