Subject: [PATCH] ruby.withPackages: preserve setup hooks (#72743)

This fixes

    nix-shell -p 'ruby.withPackages (const [])' ruby.devdoc

which otherwise wouldn't find documentation, unlike

    nix-shell -p ruby ruby.devdoc

which would, because ruby has setup hooks to accomodate for this, that
were being masked by the withPackages wrapper.
