Subject: [PATCH] chore(nix): make sure ruff is runnable on NixOS

Before `devenv`'s been introduced, `autoPatchelfHook` made sure that
external binaries are executable. `Devenv` has its own magic sauce
that makes Python dependencies "just work", however `ruff` is not a
python binary, so it needs special care.
