CI Job to test links in markdown files (and documentation)
Super low priority. Only progress when ultra bored or negative motivation for anything else.
We talked about whether we should link to other files in the repository with relative or absolute URLs. The readme.md is used in pypi site as well, and relative links don't work.
This brought up the idea, to generally check all (external / absolute) links via CI: https://stackoverflow.com/questions/67924428/how-to-check-dead-links-in-a-gitlab-ci-job-which-builds-a-static-site-with-mkdoc
Additionally we could add a CI job that adds a branch that turns relative links into absolute links for use in pypi.
