hyprlock is broken after hyprland's migration to lua

`hyprlock` module references [hyprland source](https://github.com/catppuccin/hyprland), expecting a .conf file with the color palette, but it doesn't exist anymore https://github.com/catppuccin/nix/blob/2084c545f5150584ccb5b1d03fefb345155ecb29/modules/home-manager/hyprlock.nix#L31
