Make dedicated installation instructions for fonts

[MaddyGuthridge]

When I search for font packages, the search tool provides the same installation instructions as it does for other packages.

  environment.systemPackages = [
    pkgs.liberation_ttf
  ];

However, as per the NixOS Wiki, fonts should be installed like this:

fonts.packages = with pkgs; [
  liberation_ttf
];

It would be helpful to make the package search tool provide correct installation instructions for fonts.

I agree that would be great! Would you be up for creating a PR?

I'm happy to try, but am unsure of an approach that would work. Can you think of a reliable way to tell if a given package is a font?

Hmm, I don't see an obvious way to tell either.
