hook_ranking() has been renamed to hook_node_search_ranking()

hook_ranking() has been deprecated in Drupal 11.3

The hook has been renamed to hook_node_search_ranking(), and it works exactly the same. Until Drupal 12, both hooks will be supported.

Before

<?php
/**
 * Implements hook_ranking().
 */
#[Hook('ranking')]
public function ranking(): array {
  ...
}
?>

After

<?php
/**
 * Implements hook_node_search_ranking().
 */
#[Hook('node_search_ranking')]
public function ranking(): array {
  // Same function body as before; just change the function name.
}
?>
