title: Remove header title from react-navigation
body: <p>I'm using <code>react-navigation</code> version 6 and would like to know how to remove that title from the header, which comes by default, already displaying the name of the page that we pass.</p>
  <p>In version 5, passing to <code>headerMode</code> this was already removed, but in this new version I didn't find how it can be removed.</p>
  <p>My code:</p>
  <pre><code>import React from 'react';
  
  import { createStackNavigator } from '@react-navigation/stack';
  
  import { Home } from '../screens/Home';
  import { Search } from '../screens/Search';
  
  const { Navigator, Screen } = createStackNavigator();
  
  export function AppStackRoutes() {
    return (
      &lt;Navigator initialRouteName=&quot;Search&quot;&gt;
        &lt;Screen 
          name=&quot;Search&quot; 
          component={Search} 
        /&gt;
        &lt;Screen 
          name=&quot;Home&quot; 
          component={Home} 
        /&gt;
      &lt;/Navigator&gt;
    )
  }
  </code></pre>
