🐛 Describe the bug

There is a dead link https://github.com/pytorch/torchchat/blob/main/torchchat/utils/quantize.py#L1260-L1266 in https://github.com/pytorch/torchchat/blob/main/docs/quantization.md like See the available quantization schemes [here](https://github.com/pytorch/torchchat/blob/main/torchchat/utils/quantize.py#L1260-L1266).. Could you please help update it to show the quantization schemes examples?

Link looks live to me (redirects to code)?

That said we doc in the file can be polished
