flake: allow using nixpkgs lowdown 3.0

Browse Source 
Admittedly, I do not understand what the comment means:

> As soon as Nixpkgs updates to >= 3.0.0, change to lowdown_2_0!

But this should work fine for nixpkgs versions providing lowdown 2.x or
3.x, and not cause rebuilds of the nixpkgs Lix/Nix derivations.
