Automatically install Lefthook during setup

[No767]

Summary

To make life easier, instead of running the lefthook install command after you install the npm deps, we just do it inside of an script right after installation. This also prevents me from reminding folks to do that constantly. Kinda of a neat and handy trick tbh.
