lib/options: Relax showOption quoting
https://github.com/NixOS/nixpkgs/commit/124cccbe3b63122733e02e41e45a383ec48752fd broke the build of NixOS manual. It does not make sense to be as strict as with attributes since we are not limited by the CLI's inability to handle numbers. Placeholders should not be quoted either as they are not part of Nix syntax but a meta-level construct.
