Describe the need of your request

Aspire 9.3 introduced the integration of Github Copilot inot the dashboard.

Unfortunatly, this feature is still not working when starting the Apphost from JetBrains Rider, and failing with the following error:

fail: Aspire.Hosting.Dashboard.Model.Assistant.AssistantChatViewModel[0]
      Error getting GHCP info.
      System.InvalidOperationException: Error response from GHCP.

Hi! I'm not sure that this is possible. VS and VS Code probably have a GitHub Copilot executable or something, and our plugin doesn't have one. And I'm not sure that it is legally possible to launch Copilot from our plugin.
