Diffrax v0.6.2

• Updated to silence warnings from JAX 0.4.38 (jax.core.Jaxpr -> jax.extend.core.Jaxpr) (Thanks @jakevdp! #544, #546)
• Added diffrax.ForwardMode for efficient forward-mode autodifferentiation through diffeqsolve. Updated docs to reflect that there are now two main recommended choices, namely ForwardMode for forward-mode and RecursiveCheckpointAdjoint for reverse-mode. (Thanks @johannahaffner! #537)
