Included missing notebook in the viz docs

[pfebrer]

I don't know why, but there was a notebook that was not included in the .rst file (probably I forgot to include it).

[pfebrer]

Thanks! Could you refresh the documentation? I'm writing a message on discord to advertise the new sisl.viz :)

Is it important to get out now? It could be great to get #629 in as well? Shouldn't take too much

[pfebrer]

Hmm ok, I'll just save the message

[zerothi]

I am quite worried about my limits on the CI's, not infrequently I get emails on having runned too much :)
That is why I am trying to limit unnecessary runs. Hope you understand!
(you can print it here for safe keeping? )

In the case of documentation I think it would be worth to have some caching, specially of the executed notebooks. (the hardest point would be to keep track of which parts of sisl the notebook depends on)

[zerothi]

Agreed, I haven't had time to look into GA caching... But that would indeed be great!
