Generic packages project-level duplicate setting
Problem to solve
When using the GitLab Package Registry to publish Generic packages, a duplicate package name/version can be uploaded. In #293755 (closed) we added a setting to disable duplicates at the namespace level, however, it would be beneficial to have a more granular setting at the project level so certain projects can override group settings and the entire group does not have to be enabled or disabled.
Proposal
Add a setting that will allow you to define (at the group level) whether or not duplicate Generic packages are allowed at the project level.
