Should we add ngi-nix/ngipkgs to nixos search?

It looks to be as simple as adding it here https://github.com/NixOS/nixos-search/blob/main/flakes/manual.toml and it looks like there are some other ngi-nix org repos there already.

Perhaps this could have helped us avoid https://github.com/ngi-nix/summer-of-nix/blob/a640251153b4d20c1aa3c05ba95be077d635dede/2023/report.md?plain=1#L53-L54

I'm not sure if it would really have helped avoid the duplicated work, because it was simply an oversight by me that could have been avoided by more diligent review of sources.

I'm also not sure the flakes search actually works. At least I can't find anything with it.

I hope that #166 would at least partially address the problem at least partially automated.
