The SortBy enum does not get generated as a C# enum.

Run the C# generator against the embedded OpenAPI example, focusing on the inline enum used by the sortBy parameter. Inspect the generated client output and the generator's handling of embedded enums; done means SortBy is emitted as a C# enum rather than being omitted or represented only as a string.
