This simplifies the docs-check workflow definition by extracting functionality
directly coded into the workflow file into new make targets 'check-docs'
and 'check-helm-docs' and replacing the code in the workflow file by the simple invocation of
new make targets. As a side effect, it makes it easily possible for a
developer to check locally if they forgot to commit any autogenerated
docs.
