Sidebar Layout on Mobile

[madphysicist]

The current layout of numpy requires me to scroll through about three full screens of what should be side-bar material. I am currently using Firefox 68.7.0 on a Motorola e5. The issue does not seem to be limited to my phone or browser.

Here is a screenshot of np.roots as an example:

While the new navigation info is sometimes useful, I'm not sure it's the first thing that should be shown on mobile, ahead of the main content.

This is a replica of numpy issue numpy/numpy#18549, appears to be related to #317

Matplotlib has this problem too. We are removing the left sidebar content as it is largely redundant with the right sidebar, and makes mobile very hard to use.
