Subject: [PATCH] Add appSettings field and CreateQuestionAsync method

The `ChatService` class now includes a private readonly field `appSettings`, initialized via the constructor. A new method `CreateQuestionAsync` has been added to handle question creation asynchronously, leveraging chat history. Additionally, a comment has been updated for clarity regarding chunk limitations.
