Improvements to WPF-UI.Tray NotifyIconService Functionality

Is your feature request related to a problem? Please describe

The NotifyIconService allows activating a NotifyIcon independently without requiring a XAML file.
Currently, the method used to automate the disposal of InternalNotifyIconManager is to register a parent window so that InternalNotifyIconManager is disposed when the window’s Closing event occurs.
However, users often rely on the Window.Closing event to determine whether the window should actually be closed, and they may decide to either proceed or cancel the operation.
Therefore, if NotifyIconService intends to dispose InternalNotifyIconManager through the parent window, it seems more appropriate to use the Closed event rather than Closing.

Describe the solution you'd like

Wpf.Ui.Tray(4.2.0.0)
Wpf.Ui.Tray.NotifyIconService

AS-IS

public void SetParentWindow(Window parentWindow)
{
    if (ParentWindow is not null)
    {
        ParentWindow.Closing -= OnParentWindowClosing;
    }

    ParentWindow = parentWindow;
    ParentWindow.Closing += OnParentWindowClosing;
}
private void OnParentWindowClosing(object? sender, CancelEventArgs e)
{
    internalNotifyIconManager.Dispose();
}

TO-BE

public void SetParentWindow(Window parentWindow)
{
    if (ParentWindow is not null)
    {
        ParentWindow.Closed -= OnParentWindowClosed;
    }

    ParentWindow = parentWindow;
    ParentWindow.Closed += OnParentWindowClosed;
}
private void OnParentWindowClosed(object? sender, EventArgs e)
{
    internalNotifyIconManager.Dispose();
}

Start in the Wpf.Ui.Tray NotifyIconService implementation and inspect SetParentWindow and its parent-window event handler. Change the disposal trigger to the parent window's Closed event, then verify that disposal occurs after the window closes rather than when closing is cancelled.
