Explain how ENV variables work

[adrians5j]

We had a question from a user who was a bit confused how the .env.json files work.

We must create an article which will give an overview of all files, explain how the inheritance works and how they are used - both by users that deployed a new project, and by other team members who are just cloning the project on their own project and starting from there.

Hopefully, we'll also transform our .json files to .js, so we'll be able to add comments in the actual files as well.

I'll try to make the transition to .env.js in the following days. I think it's just a matter of renaming the files and using module.exports = {}. I'll take care of that.
