Subject: [PATCH] Remove retired files

MWE file is pretty useless, and build hooks aren't needed anymore without Docker Automated Builds

-# The image name should be of the form 'namespace:tag', e.g.
-# 'yourname/yourproject:latest', see also https://docs.docker.com/docker-hub/builds/advanced/.
-#
-# If $IMAGE_NAME is defined as an environment variable, it takes precedent and the
-# command line argument image name will be ignored.
-# If neither is given, this script fails.
-
-# In 2021, Docker retired its free automated builds. They now require a Pro plan.
-# (We can thank abusive miners for that).
-# To cope, and to not have to pay, these images are now built locally and pushed
-# manually. Hence, this script now works for both local use as well as DockerHub use
-# (should a Pro plan be available).
