Wrong locale display text of DatePicker with GraphicalDatePickerStyle style

the reproduce code is very simple, just drag a DatePicker and set locale to another one(not default or en, zh-CN here), you will see the display texts like all week day name and Time are not translated to Chinese,still english, here is the image of it:

Code Block swift
 DatePicker(selection: .constant(Date()), label: { Text("Time") })
        .datePickerStyle(GraphicalDatePickerStyle()).environment(\.locale, Locale.init(identifier: "zh-CN"))


and there is another issue actually , it show 12 hour format even your device setting is 24 hour.
