Reworked API reference doc (#9536)

This PR contains API reference docs generated from the reworked
generator (see:
kubernetes-sigs/reference-docs#53).
The main purpose is to rework the way how examples are shown.
When we are happy with the revised version, we can move the CSS and
fonts file to the static directory. We only need to change the HTML
and the `navData.js` file in the future.
