Use Ubuntu 22.04 images for the latest k8s versions.
Created by: chess-knight
This uses Ubuntu 22.04 starting from 1.25.11, 1.26.6 and 1.27.3 as discussed in #409 (closed).
These images are working Ubuntu 22.04 images also with a small qcow2 disk size ~4,35GB. Also thanks to @berendt for rebuilding them after the upstream merge.
Working images are also versions >= v1.24.14, v1.25.10, v1.26.5, v1.27.1 but these images have big disk size (~11,6GB on average) and have some problems with converting to raw, see this comment. So I decided not to use them for 2204.
Fixes #409 (closed)
