docs build fails

[dfguerrerom]

There is an error with the documentation build as it can be seen here:
https://readthedocs.org/projects/sepal-ui/builds/24339120/

Could not import extension jupyter_sphinx (exception: lxml.html.clean module is now a separate project lxml_html_clean.

arf this seems to be related to jupyter_sphinx itself that I am supposed to maintain as well

Actually it continuous failing in readthedocs... I have opened a new PR to test it: #930

The error is not the same as the previous, that one was fixed with 965da70, the issue now is:

  Exception occurred:

m2r2 have not been updated for a year , incompatibility with latest docutils is to be expected. Can you trace back to where the m2r2 package is called ?
