Update using_docker_images.md to explicitly note that default environment...
What does this MR do?
Recently when trying to get a linked service container to leverage information provided as environment variables, it became clear that only explicitly provided environment variables are passed along to linked containers. And that this does not include variables available by 'default' as provided by Gitlab CI
I'm hoping to clarify things for other folks who might run into this issue and be as confused as I was.
What are the relevant issue numbers?
