docs(nixery): replace the Nixery mdBook with a simple web page r/5116

Nixery's previous landing page was an mdBook that was basically
unmaintained and full of incorrect information. It also duplicated
some things (like nix-1p) which actually live elsewhere.

This commit removes the mdBook completely and reduces it down to a
simple TVL-style landing page. The landing page has been checked in
in its entirety because Nixery is frequently cloned through josh
without the entirety of depot, however the page has been created by
building it through depot's //web/tvl/template.
