Subject: [PATCH] editors/code: fix nixos detection

Problem: NixOS started using quotes around it's id field in /etc/os-release
Solution: Parially parsing os-release, and detecting, whether `nixos` appears anywhere in "ID=" field\
See https://github.com/rust-analyzer/rust-analyzer/issues/11695
Closes #11695
