Invalid exception when add-collaborator return 201

[FrediKats]

From docs (https://docs.github.com/en/rest/collaborators/collaborators#add-a-repository-collaborator):

But .Add method has response.HttpResponse.IsTrue() and fail on 201. Method should return RepositoryInvitation instead of bool and do not fail on 201.

We will try to fix it.

If you don't have time or if you run into any issues, let us know and we can try to pick this up on our side.

I imagine this will end up being a breaking change as the return type will be different.

This issue was originally posted in #2373, but the author had lost the confirmation of this problem somehow.

I can try to create a pull request to fix it in a few hours.
