Code Review
This pull request adds a new documentation page for JaxTrainer, which is a great addition. The guide provides a good overview of the API and how to use it with TPUs. I've made a few suggestions to improve the document's correctness and consistency, mainly around fixing some formatting issues, correcting a version number, and aligning the code examples with the recommended public APIs. Addressing these points will make the guide clearer and more accurate for users.

We should add these to the API references so we can link them here.

I added it in f634b93., I only linked it in two places though not every time I used JaxTrainer since it seemed excessive.
