Missing "source_module property" annotation

Error:
[error] The d7_nodesubqueue plugin must define the source_module property.

Steps to recreate:
Install Nodequeue Migrate and run drush ms

Reason:
Somewhere between 8.3 and 8.5 Drupal changed and modules now need a source_module property in their annotation.

Proposed solution:
Update the annotations of NodeSubqueue.php and NodeQueue.php as shown below.

NodeSubqueue.php

/**
 * Drupal 7 nodesubqueue source from database.
 *
 * @MigrateSource(
 *   id = "d7_nodesubqueue",
 *   source_module = "node",
 * )
 */

NodeQueue.php

/**
 * Drupal 7 nodequeue source from database.
 *
 * @MigrateSource(
 *   id = "d7_nodequeue",
 *   source_module = "node",
 * )
 */
