I disabled mod_shib in https://github.com/MaRDI4NFDI/docker-wikibase/commit/03e66407e61eda10d3c84acabe3c9dcf7559935f let's see if that helps

When we are at it, I also wanted to update to the most recent WMF branches (c.f., b5f497f6d493695208d334b7fd8cbb0471c6b64a)

That did not help, the error is still the same

Juhu, eventually I can go to the park;-)
