default keyboard layout

[Estirp]

When I started hyprland after removing my old syntax configuration (.conf), the new generated hyprland.lua conf come with

hl.config({
    input = {
        kb_layout  = "us",

However,
localectl show
X11 Layout: fr
and
/etc/vconsole.conf
contains
XKBLAYOUT=fr

I do not know which standard way hyprland should use to take the keyboard, but I think it should take one, probably one of the aforementioned. And if no keyboard is configured in the system, it could take, maybe, the "us" one.
I think the generated config file should default contains
kb_layout = "", which should correspond to, by order

1. the system keyboard
2. the us one

And only if someone write a value inside kb_layout, take the value(s) inside.
