Update notebooks for SimPEG v0.23.0 (#30)

Collect changes required to update the tutorials to work with SimPEG
v0.23.0. Use `choclo` as engine in gravity and magnetic simulations, and
add it to the `environment.yml`. Replace `indActive` for `active_cells`
in potential field simulations. Replace `Update_IRLS` for `UpdateIRLS`.
Use `diagonal_balance=True` when defining a `TreeMesh`. Rely on the
default solver capabilities. Bump SimPEG version in landing page and in
the `environment.yml`. Use Numpy's RNG instead of global seeds.

Include changes from #29, #31, #32, #33.

Fixes #28
