This adds a step-by-step guide to install a dev setup based on
WSL2 / Ubuntu and native VS Code with the WSL extension. The guide
uses screenshots and adds annotations on top using Inkscape, so that
every click is documented.
The Inkscape sources are also added to allow adjusting / fixing the
annotations later on without having to record a new set of screenshots.
