feat: Create tiny config for GPT-NeoX for quick tests

The main zero1.yaml uses a config that exceeds the allocation limit of existing AWS machines. Here we create a tiny yaml to allow quick testing.

Test:
```
det experiment create zero1_tiny.yaml .
```

 Once a cluster is available, run the following command: 
 ```
-det experiment create zero1.yaml .
+det experiment create zero1.yaml . # For full training
+det experiment create zero1_tiny.yaml . # For quick tests

 **Note:** You will need to run on GPUs that support fp16 training.
