docs: regenerate highlight style and streamline background overwrite

 * Update to rougify 3.26.1 styling
 * Adapt background overwrite by removing default background color
   and only adding explicit overwrites for syntax error
   (error stylings appear for example in json-excerpts –
   see HACKING.md – and are therefore hidden by our css)
