[feature request] nixpkgs goto definition

[aaronjanse]

It would be cool to be able to "goto definition" for packages and maybe even goto for nixos options. This might require that the edited expression is a Nix Flake.

I have a break from university this week, so I'm willing to put a lot of effort into implementing this. I thought it would be good to document the feature request here in case there's a huge roadblock I'm missing etc, if the implementation is already in progress, or if there's another reason to not do this.

Cheers :-)

@aaronjanse I guess it may be somehow possible to use the logic from e.g. builtins.unsafeGetAttrPos.
