Add models wisely

Recently I noticed that Copilot added a Models label in Settings. It allows user to add specific models or some model providers.

It is great. However, I think there is something can be improved. For example, now we can just add specific online models. But maybe we need local model like ollama. Also, we may not need to add each model specifically, we just need to add two, OpenAI API like and Claude API like, that is enough. We just need the url and api key, and the calling model name.
