docs: Make the generated docs visible.

There is still a lot of improvements that could be made to make the
generated docs better organized.  However, before this change we were
generating the docs but they weren't in the doc tree so you couldn't
actually browse to them.  So we fix that first so that we can start
getting feedback about how to organize them.

+used by the LMS and Studio.  This is a legacy code organization decision, and
+it is currently intended that most of the code here will eventually either be
+moved into the ``openedx`` package or broken out into a separately installed
