Simplify / fix our yard doc Rake task

We were trying to parse out a readme file that doesn't exist and the license file which produced errors
We namespaced the task in a way we don't do anywhere else. This matches our other gems now
Tell people to use bundler in the errors instead of gem installing things
We required rubygems which is not necessary
