refactor!: move whiskers to catppuccin/whiskers

I've removed all configuration relating to whiskers in the flake.nix but I think that means this will instantly start breaking if users try to upgrade without changing their input.
(Since catppuccin-toolbox.packages.${pkgs.system}.whiskers would not longer exist. )

I'm assuming we want to go about this in a way that's nicer to nix users?

cc: @nullishamy @isabelroses @getchoo - would appreciate your inputs :D

You should probably add a builtins.throw "This package has move to x location"; Though this doesn't seem to easy to add seeing what has changed here.

[getchoo]

-packages = forEachSystem (pkgs: lib.filterAttrs (_: v: lib.isDerivation v) (pkgs.callPackage ./nix {}));
+packages = forEachSystem (pkgs: lib.filterAttrs (_: v: lib.isDerivation v) (pkgs.callPackage ./nix { }) // { whiskers = throw "This package has been moved to x `github:catppuccin/whiskers`"; } );

and for the overlay

{
  catppuccin-whiskers = throw "This package has been moved to x `github:catppuccin/whiskers`";
}

this is the best way i could think of without refactoring the flake, as it's pretty brittle with this structure
