Nix (home-manager) configurations for my computers
Disable ligature on kitty (entirely)
be68a00326f0cfd704bc7fd3f2b6a92dcb72073f does only disable ligature
for regular style: italic (e.g. comments) and bold style still use
ligatures.
I had to use `extraConfig` because Home Manager's Kitty configuration
incorrectly models `kitty.conf`. Home Manager only accepts attrset
with string, boolean, or integer value but `kitty.conf` allows
specifying same key multiple times.
