title: drawer navigator - add a screen without displaying in the drawer
body: <p>I wanna be able to add <code>Drawer.Screen</code> inside <code>NavigationContainer</code> but don't want to display on the drawer.</p>
  <pre><code>&lt;NavigationContainer&gt;
      &lt;Drawer.Navigator initialRouteName=&quot;Search&quot;&gt;
        &lt;Drawer.Screen name=&quot;Search&quot; component={SearchScreen} /&gt;
        &lt;Drawer.Screen name=&quot;Notifications&quot; component={NotificationsScreen} /&gt;
        &lt;Drawer.Screen name=&quot;DetailScreen&quot; component={DetailScreen} /&gt;
      &lt;/Drawer.Navigator&gt;
    &lt;/NavigationContainer&gt;
  </code></pre>
  <p>I don't want to display <code>DetailScreen</code> in the drawer, but want to keep it so that I can navigate to this screen inside my components.</p>
