With OSH now publishing charts regularly with each change, there
needs to be a way to track these changes in order to track the
changes between chart versions.
This proposed change adds in a reno check job to publish notes
based from the changes to each chart by version as a way to
track and document all the changes that get made to OSH
and published to tarballs.o.o.
