few shot reversed in get_messages_from_history

Please provide us with the following information:

This issue is for a: (mark with an x)

- [x] bug report -> please search issues before submitting
- [ ] feature request
- [ ] documentation issue or request
- [ ] regression (a behavior that used to work and stopped in a new release)

Minimal steps to reproduce

I noticed that the few shot messages are inserted in reverse order within the conversation, is this a desired behaviour? By not specifying the index in the append_message function, they are all inserted in the first position, reversing the list.

Expected/desired behavior

You can quickly fix this by changing the line 338 of chatreadretrieveread.py to "for shot in reversed(few_shots):" or by specifying the index in append_message

Thanks! We'll be in touch soon.

Thanks for catching that! I don't think that was intentional, I've sent a PR with a fix: #852
