GetPage PreventDuplicateHandlingMode is reset to default when used in navigator2 (Getx5)

[linpengteng]

Describe the bug
GetPage PreventDuplicateHandlingMode is defined but has no effect when used in Naviger2, still uses the default PreventDuplicateHandlingMode.reorderRoutes

Reproduction code
When using Get.toNamed, one of the APIs (_configureRouterDecoder) uses copyWith of GetPage, causing PreventDuplicateHandlingMode to be lost

  // no PreventDuplicateHandlingMode
  GetPage<T> copyWith({
    LocalKey? key,
    String? name,
    GetPageBuilder? page,
    bool? popGesture,
    Map<String, String>? parameters,
    String? title,
    Transition? transition,
    Curve? curve,
    Alignment? alignment,
    bool? maintainState,
    bool? opaque,
    List<BindingsInterface>? bindings,
    BindingsInterface? binding,
    List<Bind>? binds,
    CustomTransition? customTransition,
    Duration? transitionDuration,
    Duration? reverseTransitionDuration,
    bool? fullscreenDialog,
    RouteSettings? settings,
    List<GetPage<T>>? children,
    GetPage? unknownRoute,
    List<GetMiddleware>? middlewares,
    bool? preventDuplicates,
    final double Function(BuildContext context)? gestureWidth,
    bool? participatesInRootNavigator,
    Object? arguments,
    bool? showCupertinoParallax,
    Completer<T?>? completer,
    bool? inheritParentPath,
    bool? canPop,
    PopInvokedWithResultCallback<T>? onPopInvoked,
    String? restorationId,
  })

To Reproduce
None

Expected behavior
Allow GetPage PreventDuplicateHandlingMode to be customized and used in navigator2
