GtkGrid maybe shouldn't use "left"
Mentions of "left" and "right" were remplaced by "start" and "end" in many places in the API to work as well on RTL as it does on LTR. I noticed GtkGrid still uses "left" and "top" to refer to positions in GTK 4, maybe they could be replaced by "x-attach" and "y-attach", or "h-attach" and "v-attach".
