20497: Direct the reader to the tutorial project via Public Favorites

Unfortunately searching for the project raises a couple of issues:

* The search results return two copies of the project, one from pirca
  and one from jutro. If the reader picks the jutro one, they'll be
  prompted to log in again, losing their progress and kicking them off the
  happy path.

* The search results also return the finished demo workflow process we
  publish for people, "(start here) Example WGS processing workflow". This
  is attractive to people because it says "(start here)", has a bright
  green "Completed" badge next to it, and the difference between a process
  and a project may not be clear to people who are just getting started
  with Arvados.
