Outdated ilab directory layout after initializing your system for Mac

[jwm4]

The ilab directory layout after initializing your system documentation seems inconsistent with itself and with what I observe when I setup ilab on MacOS. I pointed this out on Slack, and @nathan-weinberg pointed out the following:

I think the docs are out-of-date, IIRC Jaideep Rao changed this here: instructlab/instructlab#2202

JJ Asghar also pointed out:

This thread has more information too:

So I think the documentation needs to be updated accordingly.
