BUG: Fix language model type in rc schema

[waldekmastykarz]

We need to fix the

dev-proxy/schemas/v0.27.0/rc.schema.json

Line 58 in f61443e

"LMStudio",

schema. Instead of LMStudio, we should have OpenAI to match:

dev-proxy/dev-proxy-abstractions/LanguageModel/LanguageModelConfiguration.cs

Lines 7 to 11 in f61443e

	public enum LanguageModelClient
	{
	Ollama,
	OpenAI
	}
