<!-- Thank you for your contribution! -->

## Why are these changes needed?

Together has recently released the v1 model, and we might want to update the model information accordingly. 
Model card: https://huggingface.co/togethercomputer/RedPajama-INCITE-7B-Chat
Release blog: https://www.together.xyz/blog/redpajama-7b

The redpajama adapter has already been added through #1319. Therefore, the only updates required would be to the model link and register.

I run this cmd and it works out-of-the-box.
```bash
python3 -m fastchat.serve.cli --model-path togethercomputer/RedPajama-INCITE-7B-Chat --debug
```

Please let me know if there are any other actions that need to be taken.
