Translations are imported in a consistent order

Prior to Drupal 10.3.0 translations where imported in an inconsistent order.

In Drupal 10.3.0 translations will be imported in alphabetical order by the translation project name. The order can be changed by adding a weight key to the translation project using hook_locale_translation_projects_alter.

Example

function my_custom_module_locale_translation_projects_alter(&$projects) {
  if (isset($projects['existing_project'])) {
    // Move this project to the end of the list of projects to be imported.
    $projects['existing_project']['weight'] = 100;
  }
}

This example changes the weight of the translations to 100.
