en_GB incorrectly resets to en_US for date pickers

[yunruse]

As can be seen, US-style date pickers are being used – the week starts on Sunday rather than Monday; the date is MM/DD/YYYY rather than DD/MM/YYYY – even though for this screenshot the language is set to en_GB. Because the localisation file is en.lproj, the following branch is followed no matter what, resetting localisation to en_US:

reminders-menubar/reminders-menubar/Resources/remindersLocalized.swift

Lines 108 to 110 in d92d205

	if Bundle.main.path(forResource: currentLocale.identifier, ofType: "lproj") == nil {
	// Return the default locale if translation to system language does not exist
	return Locale(identifier: "en_US")
