#131 website: give the links to docs/ a better description

Right now the website produces this:

See ../docs/#version

where "../docs/#version" is the link. In my opinion it doesn't look good and would be more approachable if it would be like

See "docs: version"

and similar links.

Better would be a descriptive name...

Of course, I just made an example. I did not want to provide one solution.
