Tutorial: JAX Export to StableHLO (#2232)

See tutorial rendering using "View File"
([example](https://github.com/openxla/stablehlo/blob/f85d9fffc3d4e0fe4f09bfadd4739d09baaf60c1/docs/tutorials/jax-export.ipynb)).

Once merged the "Open in Colab" button should work. Also once integrated
this should appear on the openxla.org documentation as well.
