Hard to find and validate a link

[almereyda]

We now have a link checker workflow that runs every time when we deploy next.

Its outputs are amended to the Pull Requests that yielded their execution:

• fix(lychee): do not check mailboxes' deliverability #24
• Pull in latest changes from main to next #25

Notice that everywhere you see public/ in the paths, you can replace it with https://next.degrowth.net/ to check the path on the actual site. This is currently a limitation of Lychee, our link checker (which otherwise performs very well).

• Add recursive option lycheeverse/lychee#78

We can work around this limitation by modifying the generated files to a more useful state, before they are commented back to the PR.

#27 implements the desired modification.
