[SYSTEMDS-3271] Publish docker test image when requested

Adds a new docker-testImage.yml to allow manual initialization of building
our test image. This allows us to update the image used in our github
actions if for instance a new R package is added.

This commit also slightly modify the docker action to also build
the python image, when the default night cpu build is made.
