Looks good, I just have one comment below, let me know what you think.

This should preferably be just "ur", unless Urdu (Pakistan) is different enough from Urdu (India) that it needs to be translated separately.

Suggested change

	"ur_PK" => [
	"ur" => [

Hi. So there are a few structural differences between the two versions and there are some words as well that are either spelt differently or are totally different. I think it would be better that they are kept different, but later on if someone comes in to translate for "ur" I think they will be able to alias this if they believe ur_PK works for that version too.

Sounds good 👍
