system_get_info() is deprecated in drupal 9
I'm not sure what I did to trigger the error and I don't see it on d9-master.demo, but the function is clearly not in drupal 9 (https://api.drupal.org/api/drupal/core%21modules%21system%21system.module/function/system_get_info/8.8.x).
I'm just still trying to figure out how to reproduce an error consistently.
Error: Call to undefined function system_get_info() in CRM_Core_Permission_Drupal8->getAvailablePermissions() (line 61 of ...\vendor\civicrm\civicrm-core\CRM\Core\Permission\Drupal8.php).
