hook_form_FORM_ID_alter hooks are not converted to OOP

Drupal version

11.2.2

Drupal Rector version

0.21.0

Problem / Motivation

We are using rector to convert hooks. It works with most hooks but hook_form_FORM_ID_alter hooks are not converted.
For example:

/**
 * Implements hook_form_FORM_ID_alter().
 *
 * @phpstan-param mixed[] $form
 */
function foo_form_menu_link_edit_alter(&$form) : void {
 //
}
