doc: document how to get flat html doc files

The documentation instructs to use:

  bazel build Documentation:searchfree

Which results in a zip file one has to extract before browsing. I did it
with an inotify hook but that is cumbersome.  Instead one can just call
the parent target `Documentation` which does not zip files:

  bazel build Documentation
  xdg-open bazel-out/Documentation/index.html

It is probably obvious to everyone, but might be a barrier of entry
toward adding more documentation.

Also specify the `withdocs` target is to build the Gerrit WAR.
