Do not use broken 3.22 docker image
Created by: Rikuoja
Looks like the QGIS executable is not present in the 3.22 docker qgis build release-3_22
since version 3_22_10. This causes pytest to fail, qgis is not found: https://github.com/qgis/QGIS/issues/50729
So let's use the latest working 3.22 docker image.
