title: Android viewbinding deprecation warning persists in Android Studio 4 after making appropriate update
body: <p>After updating to Androis Studio 4.0 I received a warning that <code>android.viewBinding.enabled</code> was deprecated and shoud lbe replaces with <code>android.buildFeatures.viewBinding</code>.</p>
  
  <p>I therefoe changed the appropraiet part of my <code>build.gradle (app)</code> from:</p>
  
  <pre><code>android {
      ...
      viewBinding {
          enable = true
      }
      ...
  }
  </code></pre>
  
  <p>to:</p>
  
  <pre><code>android {
      ...
      buildFeatures {
          viewBinding {
              enabled true
          }
      }
      ...
  }
  </code></pre>
  
  <p>I no longer get the warning, but still get an information box in my build window as follows:</p>
  
  <p><code>build.gradle: DSL element 'android.viewBinding.enabled' is obsolete and has been replaced with 'android.buildFeatures.viewBinding'.
  It will be removed in version 5.0 of the Android Gradle plugin.</code></p>
  
  <p>Is this normal? I knows it's not a warning or an error, but it seems odd to tell me about something that has been fixed - or have I not fixed it correctly (my app still works using viewBinding as expected).</p>
  
  <p>(Note also that when adding the <code>buildFeatures</code> section to the file, none of the required entires, including <code>buildFeatures</code> pops up in teh auto-complete prompt.)</p>
