Change max_position_embeddings to original value

max_position_embeddings in this config was set to 16384, which seems to be an error (this is exactly the same as hidden_size) and should actually be 131072. In both the [original model config](https://huggingface.co/meta-llama/Llama-3.1-405B/blob/main/config.json) and the [AWQ-quantized config](https://huggingface.co/hugging-quants/Meta-Llama-3.1-405B-Instruct-AWQ-INT4/blob/main/config.json), the value for max_position_embeddings is 131072.
