"docker image rm" requires at least 1 argument.
See 'docker image rm --help'.

Usage:  docker image rm [OPTIONS] IMAGE [IMAGE...]

Remove one or more images

root@runner-21:~# docker image ls   
REPOSITORY   TAG       IMAGE ID   CREATED   SIZE

might be a good idea to delete the work directory too
rm -rf /home/*/actions-runner/_work

and we need a way to clean up the sources directory, that gains a lot in size :/
but thats something we should include in LE directly

for a hacky workaround this is good to go (likewise okayish fitting for the runners), for a "real" solution not really :)

ideally we would check for the needed packages at master + latest stable branch and delete everything else
