Create different internal vs. external sidebars, placeholder internal…

… landing page

Summary:
The staticdocs sidebar (i.e. the doc links on the left) was previously generated from directory structure.  I made it explicit here (`sidebars.js`)

Then I split it into an external and internal version using `fbContent`.   external is the same as before.  Added internal categories based on the docathon planning doc.

Also created a placeholder "generated-index" landing page which looks like this:  {F1888851708}

If we point `bunnylol redex` at `https://www.internalfb.com/intern/staticdocs/redex/docs`, it'll land on the above landing page (which can change to whatever we want), and the sidebar will have the internal topics.

The external site will go to the same landing page as before and have the same sidebar content as before.
