Also git rm -f playbooks/templates/.github/workflows/shellcheck.yml

I was wondering about the file. Since we put it in the absent_files, can we expect it will be automatically absent? https://github.com/linux-system-roles/.github/pull/13/files#diff-ee877de6bbd0a00a6b5cad8bdb7ec1f27fbb4d5d96e5e77b27a56fce75562273R12-R14

How about the individual roles which do not have shell scripts? Do we want to do git rm shellcheck.yml and merge it, too?

It will be removed from the role repos, but it also should be removed from this .github repo as well.
