title: Center Picker in View when .labelsHidden()
body: <p>I'm showing a SwiftUI DatePicker with the datePickerStyle of type WheelDatePickerStyle(). It's inside a Section, which is within a Form. As I'm showing a Section Header, I don't want to show the Picker's label. When choosing .labelsHidden(), however, the Picker just moves to the left and leaves some space to the left. </p>
  
  <p>How can I either center the picker, or make sure that it takes up the full width of the Section / Form?</p>
  
  <pre><code>DatePicker("Please enter a time", selection: $time, displayedComponents: .hourAndMinute)
      .labelsHidden()
      .datePickerStyle(WheelDatePickerStyle())
  </code></pre>
