Render Jupyter notebook in tree

[Katsuya Horiuchi]

Hi all,

Is there demand to render Jupyter notebooks in tree view?
I personally would love to see them rendered just like GitHub.

It can be achieved by calling nbconvert [0] inside the filter.
Considering there's ongoing discussion on rendering markdown files, I
think this could add additional value to cgit.

Best,
