social share previews

Locally it works fine when testing with the socialsharepreview extension though

This seems to be due to how Docsify is not a static site generator (it does client-side rendering) per page previews are not easily possible. They still can be done, but it's a bit more annoying and "hard codey".

With #12 we switched to mkdocs and with it we lost all social previews

#19 Added social previews back, and added descriptions to all guide pages.

For the API Pages the generation py needs to be adjusted.
