/**
 * Alter the list of projects before fetching data and comparing versions.
 *
 * Most modules will never need to implement this hook. It is for advanced
 * interaction with the Update Manager module. The primary use-case for this
 * hook is to add projects to the list; for example, to provide update status
 * data on uninstalled modules and themes. A contributed module might want to
 * hide projects from the list; for example, if there is a site-specific module
 * that doesn't have any official releases, that module could remove itself from
 * this list to avoid "No available releases found" warnings on the available
 * updates report. In rare cases, a module might want to alter the data
 * associated with a project already in the list.
 *
 * @param $projects
 *   Reference to an array of the projects installed on the system. This
 *   includes all the metadata documented in the comments below for each project
 *   (either module or theme) that is currently installed. The array is
 *   initially populated inside \Drupal\update\UpdateManager::getProjects() with
 *   the help of \Drupal\Core\Utility\ProjectInfo->processInfoList(), so look
 *   there for examples of how to populate the array with real values.
 *
 * @see \Drupal\update\UpdateManager::getProjects()
