docs(tvix/eval): explain where to find the site-specific mg tool

When I first read the `README.md` I didn't know what this `mg build`
was.  Some grepping around turned up `/tools/magrathea`.  Apparently
this thing "helps me build planets".  Awesome!  Let's tell other
people where to find it.  It seems that this tool is (currently)
specific to depot, so people who arrive at depot because of tvix
probably won't know where to find `mg`.
