chore(images): pin ubuntu version (#12130)

## Motivation

The `kuma-init` image fails to build on Ubuntu versions newer than 22.
To avoid this issue, we plan to use an older runner image. This problem
does not occur on the `master` branch because we use a different base
image for `kuma-init`. Additionally, on `release-2.9`, we are already
using Ubuntu 22.04.

## Implementation information

Use ubuntu 22
