 The first parameter of the `auto_update_{$type}` filter is documented as
 `bool`:
 {{{
 /**
  * ...
  * @param bool   $update Whether to update.
  * @param object $item   The update offer.
  */
 $update = apply_filters( "auto_update_{$type}", $update, $item );
 }}}

 In a few instances, as `auto_update_plugin` or `auto_update_theme`, it
 also receives `null`.

 The usage of `null` should be clarified in the docs.
