Dead links block merging

[flicksolutions]

Current Behavior

some checks fail because we have dead links: https://github.com/DHBern/dhbern.github.io/actions/runs/18757962584/job/53515010678

Found 5 broken links.

unfortunately it's hard to track where these links are...

Reproduction / Steps To Reproduce

No response

Anything else?

to fix this: find the links in the source.

i think the dead links were introduced here: #46 @vvvyyynet

@flicksolutions yes, probably, but I don't see any (internal) links in the code changed by this PR...

@maehr can you find out where in the code those links are? It's an enigma...
