Is there a better approach to listing all the samplers that PyMC supports?

I would make the list manually. I still expect a lot of people to use the pymc.sampling.jax. And we also have to be sure to test for difference between step methods and sampling functions. That is, pymc.sample(step=pymc.NUTS()) should log in the json that both sample and NUTS are used (even if we did not log kwarg values themselves, putting NUTS in another element of the samplers list).
