[Techstack-beta] Learn: How Nix Works markup

[Samuel Dionne-Riel]

Markup in commands blocks is broken:

• $ nix-env --upgrade _some-packages_
• /nix/store/s2sjbl85xnrc18rl4fhn56irkxqxyk4p-sshd\_config
• $ ./result/bin/run-\*-vm

Additionally, markup in text, starting at Reproducible system configurations, is lost.

Outline added to highlight the difference; Screenshot only shows first paragraph as an example.

btw. leaving the nixos-config snippet with the default code block theme is intentional. While highlighting the store paths in a different way makes sense, highlighting code snippets does not so much imo.
