Add experiment tracking via `trackio`

[abidlabs]

Hi folks! Would you be interested in adding experiment tracking support using trackio, a lightweight, free experiment tracking library from Hugging Face? Trackio docs: https://huggingface.co/docs/trackio/en/index

It uses the same syntax as wandb (and it is already integrated into transformers.Trainer) so the integration should be quite straightforward. The benefit of trackio is that is local-first, so users can have a nice local dashboard without needing to create an account, log in, etc.
