Feature Request: localized files should show development language first

[marcelofabri]

When selecting a localizable resource in Xcode, it'll open the first child in the editor. For example, in this case, German would be selected, even though English is the development_region

FE8B8034E620558750E6FA6E /* Localizable.strings */ = {
	isa = PBXVariantGroup;
	children = (
		FE2D9597E277009F181546EF /* de_DE */,
		FE25341A421B0B0E41DAB09F /* en */,
		FE590DC612E9434C2903CD02 /* es_ES */
	);
	name = "Localizable.strings";
	sourceTree = "<group>";
};

As far as I can tell, rules_xcodeproj sorts the languages alphabetically in

rules_xcodeproj/tools/generators/files_and_groups/src/ElementCreator/CreateGroupChildElements.swift

Lines 75 to 82 in 637a942

	func sortLocalizedFilesByNameAndRegion(
	lhs: GroupChild.LocalizedFile,
	rhs: GroupChild.LocalizedFile
	) -> Bool {
	let l = "\(lhs.name)\t\(lhs.region)"
	let r = "\(rhs.name)\t\(rhs.region)"
	return l.localizedCompare(r) == .orderedAscending
	}

.

This should prioritize the development_region so it comes first.
