npm unpublish fails to succeed during rollback process

This could be due to:

1. Permission issues with the registry token
2. GitHub Packages having different unpublish rules than npm
3. Network issues during the unpublish operation

Rollback function handled this gracefully by catching the error and continuing with the process. From a git perspective, the release was properly rolled back, but the package version still exists (not anymore, had to manually remove it) in the GitHub registry.
