We shouldn't be shipping any more dependencies on this package, as it's becoming legacy, replaced by System.Linq.AsyncEnumerable.
We'll eventually want to replace it with System.Linq.AsyncEnumerable in all tests/samples, too, but that's hard to do until SK updates to use S.L.AsyncEnumerable once its 10.0.0 version is released. I did remove the package reference from tests/samples where it's not needed.
* Update M.A.AI.OpenAI implementations
- There was only a ChatClient-based agent. Add a Responses one, too.
- Fix the public extension methods to create OpenAI types even when not backed by the right OpenAI client.
