Chat Window's `LLM Request Failed` message is too big, and unnecessary.

Does this issue occur when all extensions are disabled?: Yes

- VS Code Version: 1.136.1
- OS Version: Windows 11

Steps to Reproduce:

1. Have a poor connection or a busy LLM server.
2. When your LLM fails to respond, you get something like:

```
Sorry, your request failed. Please try again.

Client Request Id: 50ca576c-c977-44f4-a875-af2445bd0ef9

Reason: Response contained no choices.: Error: Response contained no choices. at yH._provideLanguageModelResponse (c:\Users\Farshid Mossaiby\AppData\Local\Programs\Microsoft VS Code\a44adf7f53\resources\app\extensions\copilot\dist\extension.js:1592:15149) at process.processTicksAndRejections (node:internal/process/task_queues:104:5) at async yH.provideLanguageModelResponse (c:\Users\Farshid Mossaiby\AppData\Local\Programs\Microsoft VS Code\a44adf7f53\resources\app\extensions\copilot\dist\extension.js:1592:16262)
```

Most of the message does not help at all. When I hit `Retry` it stays there, while you hide or fold much more important data. And no automatic retry if you are not in Auto-pilot mode. Even then it goes only 4 times (I am not sure if you can increase it). The next issue is that you will not get Auto-pilot if you have burnt your quota!

Should be easy to fix, right?

Thank you!
