Reviewer's Guide by Sourcery

This pull request addresses potential non-deterministic behavior in the solver by sorting sets before iterating over them. Specifically, it sorts the extras attribute of dependencies in the _search_for_url and complete_package methods within the provider. Additionally, the with_features method in DependencyPackage was updated to accept any iterable of strings instead of only lists.

No diagrams generated as the changes look simple and do not need a visual representation.
