Update README.md

### Llama3 CoEdit

This is a Llama3 8B based model trained using [torchtune](https://pytorch.org/torchtune) on the `grammarly/coedit` dataset.

### Training details

The exact training script (`lora_finetune_distributed`) and config (`8B_lora.yaml`) are both included in this repository. Specifically, in order to add the dataset, I added the following lines to the config:

```
dataset:
_component_: torchtune.datasets.instruct_dataset
source: grammarly/coedit
template: GrammarErrorCorrectionTemplate
column_map: {"sentence": "src", "output": "tgt"}
train_on_input: False
split: train
```
