Documented how to provide translations in apps, v1 addons, and v2 addons
In the docs
folder, I created 3 additional projects so that there's a living documentation (tested in CI) of how apps, v1 addons, and v2 addons can provide translations.
I also updated the documentation site. You will find new content in:
Getting Started > Overview
Getting Started > Quickstart (Apps)
Getting Started > Quickstart (Addons)
