No need to set sonatypeProjectHosting with SLRW

The `sonatypeProjectHosting` setting was full of fairly predicatible
information that is evident from the repository the code sits in - so
we can just let `gha-scala-library-release-workflow` set it for us:

guardian/gha-scala-library-release-workflow@bf9e076

...less config needed per library repo.
