Subject: [PATCH] doc: improve dark theme

This commit aims to fix some readability issues in regards to those are visually
impaired, mainly colorblindness.

- contrast of the fg/bg have been increased
- link and text have been brightened
- container objects (like the nav, <pre> background) contrast the primary
  background more.
