Fix right sidebar scrolling on documentation pages

[bobah2000]

What you were expecting: Vertical scrolling in right sidebar when there are many list items and the height of the viewport is not enough to place all of them.

What happened instead: There are no scrolling and it is not possible to click on last list items

Steps to reproduce:

1. Visit react admin documentation page https://marmelab.com/react-admin/Tutorial.html
2. Decrease the height of browser or open this page on display with low resolution

Environment

• React-admin version: 4.0.1
• Browser: Google Chrome

Thanks for reporting this!

I've reduced the font size for the table of contents. In my experience, it renders correctly even on small screens (tested with a height of 750px).

Perhaps we should simply hide the ToC for screens with smaller height.

Making it low priority though.
