When we decide we don't need to create a project we set the project
description. The reason for this is that humans like to see their
project descriptions update when they change them.
Rather than get, compare, and set the descrition we just set it under
the assumption this will be fewer requests and thus quicker. The impact
on the db likely plays into this too but our gitea dbs are mostly idle
so should be fine.
