Setup link checker for docs in CI
As a manitainer
I want to automatically check if all used URLs in docs are still valid when committing
so that we prevent dead links and solve them as quickly as possible when they happen anyway
- docs.nlx.io and appstore.commonground.nl/docs
- build fails when internal links are dead
- daily job running for link checking (only give warning in ci/cd)
- In the CI: use muffet in a container linked to the to-be-released docs container to verify all URL's to be valid.
