docs: Update docs for python bindings

[paulgessinger]

There were a few problems / oversights in the python bindings documentation. Thanks to @timadye for finding them!

Looks good. I tested the example script and it ran OK. It said it processed 10 events. The output files had no hits/tracks, but that's OK I suppose.

Hey @timadye, actually, I had left the PropagationAlgorithm stepping logger to sterileLogger=True, which makes it not accumulate any propagation steps, hence the empty files.

I've updated this PR to set that to False, this gives me non empty output now. Can you reapprove?

Cool! Now I see the propagation_steps with the "hit" positions tracing out the example detector.

I like how some low pT tracks are still individually visible.

I'm not sure of the d_x, d_y, d_z definition, but I wonder how this happens.

Sorry for the irrelevant plots. The change looks good, so I'll approve.
