Homebew Installation Documentation for Python3 Users

[GoodGuyGregory]

Problem

There are gaps in documentation for those who decide to install jupyterlab system wide using python3 +

Proposed Solution

Somewhere below this documentation. I would like to contribute documentation mentioning the newer behavior of managing a homebrew package for macOS users.

Additional context

I am installing Jupyter lab for personal Machine learning projects and would love to get started on this process, please allow me to complete this issue.
