title: How to change the default position of button tooltips in CKEditor 5
body: <p>Having a small issue with tooltips in the editor, read the api but can't understand what it is saying and I can't seem to find examples anywhere that I can understand either.
  I have set up a Classic Editor build, and all the buttons on the toolbar have tooltips with the default position below the button, I want to be able, just for this one instance of the editor, to change the tooltip position to above the buttons instead. The instance is set up like this:</p>
  
  <pre><code>ClassicEditor.create( document.querySelector( '#content' ) )
          .then( editor =&gt; {
              console.log( 'Editor was initialized', editor );
              this.annEditorInstance = editor;
          } )
          .catch( err =&gt; {
              console.error( err.stack );
          } );
  </code></pre>
  
  <p>That creates an editor instance that is set up exactly as I want, except for the issue with the tooltip. How do I change this? Thanks in advance.</p>
