Matthew Johnson 66a6eb299e add autodiff rules for jax.lax.ragged_all_to_all collective
also update the ragged_all_to_all docstring. pseudocode in the style of the shard_map tutorial would be better and cleaner, but it needs the context of the tutorial to explain; i'll add ra2a to the shmap tutorial in the future.
