docs: add Regular link check to our ci build #898
Description
#889 Added lychee configuration and scripts for link checking.
There is a workflow for offline link checks, which means only local files and not over a network. This is safer to use in CI (as checks over the internet can lead to false negatives). However, it means we are not automatically checking all links in the site.
We could use a recipe like this or this in the lychee docs to regularly check links and open an issue with the result.
