Updated with a working chat_template

After the recent README.md changes and some experimentation I have come up with the following chat_template, which I'm currently using in my [GGUFs](https://huggingface.co/CISCai/gorilla-openfunctions-v2-SOTA-GGUF).

Minor fix for [#3](https://huggingface.co/gorilla-llm/gorilla-openfunctions-v2/discussions/3), now only generates functions in last message to not waste multi-turn context.

Fixes [#2](https://huggingface.co/gorilla-llm/gorilla-openfunctions-v2/discussions/2).
