Currently, numpyro assumes keys are created using jax.random.PRNGKey. This is no longer true with the flag JAX_ENABLE_CUSTOM_RNG=1. So we need to update numpyro to enable the new-style prng key. At some point, we need to change jax.random.PRNGKey (which will be deprecated in the future) to jax.random.key. For more context, see https://github.com/google/jax/blob/main/docs/jep/9263-typed-keys.md
