Subject: [PATCH] Update docs for GridField_ActionMenuItem required parameters

I found these errors while going through this tutorial,
missing ```use use SilverStripe\Forms\GridField\GridField;```

interface GridField_ActionMenuItem required parameters on  getTitle() and getGroup()

incorrect if statement on getExtraData() - $field is not defined
