Add all config to docshelper.json

Also consolidate so the mediaTypes and outputFormats are listed once only.

Fixes gohugoio#11328

 - A page can be output in as many output formats as you want, and you can have an infinite amount of output formats defined **as long as they resolve to a unique path on the file system**. In the above table, the best example of this is `AMP` vs. `HTML`. `AMP` has the value `amp` for `Path` so it doesn't overwrite the `HTML` version; e.g. we can now have both `/index.html` and `/amp/index.html`.
 - The `MediaType` must match the `Type` of an already defined media type.
