Alit/mamba 2 0 migration
Thanks for this, looks good! My one comment is that we want to move away from scripts in the example-dir that we use inside GH-actions etc. For that, we would like to move to using a recipe (like we defined for many models [here](https://github.com/NVIDIA/NeMo/tree/e76afdfc28a1835fcf8aac97c07261e24ca0407d/nemo/collections/llm/recipes), a recipe should contain everything for training so model/data/trainer/etc.). 

We are currently working on automatically exposing those in the CLI, for more docs around that see [this](https://github.com/NVIDIA/NeMo/blob/e76afdfc28a1835fcf8aac97c07261e24ca0407d/examples/llm/pretrain/README.md) readme inside this [WIP PR](https://github.com/NVIDIA/NeMo/pull/10300).

So would be great if you could add one (or a few) recipes for this model, you could for instance take llama3_8b as an [example](https://github.com/NVIDIA/NeMo/blob/e76afdfc28a1835fcf8aac97c07261e24ca0407d/nemo/collections/llm/recipes/llama3_8b.py). > Thanks for this, looks good!
