Render jupyter notebooks in html in gitea

[robe]

Per request of darkblueb.

Steps more or less detailed here - ​https://blog.gitea.io/2022/04/how-to-render-jupyter-notebooks-on-gitea/

But had to install ipython as well so:

sudo apt install python3-pip
pip3 install nbconvert
pip3 install ipython
pip3 install docutils

and then added in the respective lines.

But I think I need to do something to enable css and strip the html cause it looks funny.

This is detailed here - ​https://docs.gitea.com/next/administration/external-renderers

and I didn't read the docs completely in the above. It does talk about styling.

You can see an example here:

There is also other things like rendering mathjax as detailed in this thread
