tqdm progressbar output messy in documentation

[OnnoEbbens]

The documentation looks kind of messy because intermediate status of the progress bar is shown:

A fix might be to disable the progress bar when creating the documentation by setting an environment variable with TQDM_DISABLE=1, see also: tqdm/tqdm#1061

Hmm, this used to be prettier:

What did we change?

[dbrakenhoff]

Maybe I changed from tqdm import tqdm to from tqdm.auto import tqdm?

But the latter option does make things much prettier for users running notebooks, with less red highlighting and such.

I do not think that is the problem, as we still use from tqdm import tqdm I think. But it may be the solution?

Another import-method is no solution, I found out from testing. I think the problem has to do with the nbconvert version. Since nbconvert version 7.14 the output is messy. See jupyter/nbconvert#2092

I will fix the nbsphinx version to 7.13 for now, and hope this will make thoe output pretty again,

Adding ipywidgets to the dependencies was also necessary.

I also made these two small changes to the main-branch, as I hoped this would fix the stable documentation as well. This is not the case, however. Then I made a branch named 'stable', which according to some webpages would fix it. This is also not the case. Finally, I temporarily set the default docs-page to the latest-version, from stable. We should change this back after the next release.

fixed in the dev branch
