registry.ddbuild.io/ubuntu:22.04 is unsigned and gets blocked by image signature verification on enforced runners, causing builds to fail.

What & Why
Our GitLab CI jobs pull
registry.ddbuild.io/ubuntu:22.04, which is unsigned. On runners with image signature verification enforced, the pull gets blocked, causing intermittent CI failures that only clear up by retrying until a non-enforced runner is picked.Switching to the signed equivalent (
registry.ddbuild.io/images/base/gbi-ubuntu_2204) avoids this flakiness.
