Lerna monorepo deployment guide

We have a new guide available for Lerna - which is a tool that helps manage monorepos.

We had a customer using it and was trying to leverage it for deployments. Turns out, it worked pretty good! The guide provides some general guidance on how to leverage Lerna for a deployment specifically for NodeJS packages.

Iā€™d love to get some additional tips for the guide if anyone would like to contribute. :slight_smile:
