This commit introduces a prepared image for setting up the WSL2
environment. This means that the deployment will take considerable
less time to finish (as it does not need to run an update and package
install), but also allows to rely on a cached image to re-init the
environment without the need for an internet connection.
[NO NEW TESTS NEEDED]
