title: UIDatepicker VoiceOver wrong accessibilityLabel
body: <p>I'm implementing VoiceOver and I have problems on iOS 13.x with the text read on datepicker values. It seems like the accessibily string are not changed after the datepicker locale is changed. 
  The column for months has the strings from US days,
  It says fünf von dreissig (5 from 30) after the April is selected, it should says 4 from 12.</p>
  
  <p>On datepicker I set 
  <code>datePicker.locale = Locale.init(identifier: "de_DE")</code> and <code>datePicker.calendar = Calendar.init(identifier: Calendar.Identifier.gregorian)</code>. I also tried to set <code>datePicker.accessibilityLanguage = "de-DE"</code>.</p>
  
  <p>Any ideas?</p>
