❄️ renames pkgconfig to pkg-config at nix files

[CarlosCraveiro]

Problem

The package previously called pkgconfig was renamed to pkg-config and was thus preventing the Tomato-C flake from being integrated into the nix powered systems.

I'm integrating Tomato-C as a overlay in my system, like this:

# At my flake.nix
# ...
       tomato-c-overlay = final: prev: {
            tomato-c = tomato-c.defaultPackage.${system};
        };

        pkgs = import nixpkgs {
            inherit system;
            config = {
             allowUnfree = true;
             permittedInsecurePackages = [ ];
           };
            overlays = [ tomato-c-overlay ];
        };
# ...

Solution

Simply rename the package from pkgconfig to pkg-config at nix files.

Additionally, I added myself to the project's flake maintainer list.
