So we made a mistake when defining our gemspec file for a ruby package which caused a large number of versions of our package to be associated with another private repository. I have read through the github packages docs and don't see a way to remove a package association from a private repository. 

Our gem no longer builds with the updated gemspec file (pointing to the correct repository) as the package is already associated with another repository (the one in which we are trying to remove the association from).
