Adding LaTeX user help

You can enable access to Overleaf's Learn pages within your Server Pro instance by simply adding OVERLEAF_PROXY_LEARN=true to your config/variables.env file in the Toolkit and running the bin/up command.

This allows users to access current documentation and learning resources by clicking the Documentation button in the navigation menu, all without leaving your instance.

For Docker Compose deployments, you'll need to add the environment variable OVERLEAF_PROXY_LEARN: true to the environment section of the sharelatex service in to your docker-compose.yml file.

Your Server Pro deployment will require access to the internet so it can perform external GET requests to https://learn.sharelatex.com.
