Refactor directory structure, update _config.yml to match opensource.guide

[ahpook]

This change updates the directory structure of the jekyll site, moving
the language-specific directories under _articles and updating the
front matter / _config.yml to match.

The goal was to clean up the root of the repository and bring the
config in line with that used by the opensource.guide site.

All LGTM. Very nice.

Non blocking question:

Do we want the index.html, businesses.html and maintainers.html now in the _articles root to be under an en directory or that will break things?

I think without more extensive surgery they need to live where they are. Based on my primitive understanding, this is because they are the default en / English versions served if the user doesn't pick a different language. Same with the index.html that remains in the repo root. It's like that in github/opensource.guide too...

That's what I guessed. Had to ask. Nice clean up and standardize.
