UseCors Must Come Before UseResponseCaching

Fixes #1106.

Now I remember why UseCors is where it is:

System.InvalidOperationException : Endpoint Health checks contains CORS metadata, but a middleware was not found that supports CORS.
 Configure your application startup by adding app.UseCors() inside the call to Configure(..) in the application startup code. The call to app.UseCors() must appear between app.UseRouting() and app.UseEndpoints(...).
