[DOCS] Steps missing in production page

[ChrisChinchilla]

I was working through the Apollo tutorial for my DXposé livestream - https://youtu.be/xkYXuIt-ZF4

And I noticed some issues with the page that connects your local running instance to your hosted services, it doesn't inject the environment variables etc… if you move towards the end of the video, you'll find the issues.
