Raito Bezarius b8cb7abcf0 chore: rebrand Nix to Lix when it makes sense
Here's my guide so far:

$ rg '((?!(recursive).*) Nix
(?!(daemon|store|expression|Rocks!|Packages|language|derivation|archive|account|user|sandbox|flake).*))'
-g '!doc/' --pcre2

All items from this query have been tackled. For the documentation side:
that's for lix-project/lix#162.

Additionally, all remaining references to github.com/NixOS/nix which
were not relevant were also replaced.

Fixes: lix-project/lix#148.
Fixes: lix-project/lix#162.
