HTML repr in the online docs

[shoyer]

I noticed two minor issues in our online docs, now that we've switched to the hip new HTML repr by default.

1. Most doc pages still show text, not HTML. I suspect this is a limitation of the IPython sphinx derictive we use for our snippets. We might be able to fix that by switching to jupyter-sphinx?

2. The "attributes" part of the HTML repr in our notebook examples looks a little funny, with strange blue formatting around each attribute name. It looks like part of the outer style of our docs is leaking into the HTML repr:

We can also switch from RST to MyST. It works quite well

I think the second point is fixed now.

Is the first point covered by #6620, albeit a more recent issue?

From what I can tell from skimming the docs it looks like this issue is fixed. 🚀

I think the issue is about stuff like this page: https://docs.xarray.dev/en/stable/user-guide/groupby.html

OK, so the idea is to have the html repr at these pages, too. Thanks for the details @dcherian .
