The guide examples are still displaying an error even though they are pre-computed

We are waiting for the implementation of readthedocs/readthedocs.org#7901 (comment) from RDT side so we can build the documentation notebook on the fly.

While it becomes a reality we decided to pre-build all of them. Even when doing this the first cell (hidden in the documentation) is displaying an error.

So why is re-executed and why does it display such a weird error message. That gives the impression that everything is broken even though everything worked just fine.
