Hide suspended users from course contacts

Moodle 3.11.x, possibly 4.x

When displaying course contacts you can see all teachers enrolled into a given course. If a user is deleted then he is not shown in course contacts, which is good. But when a user is only suspended and not deleted, then he is still shown in course contacts block.

I suggest to hide suspended users from course contacts block.

Need to modify SQL query in /course/classes/category.php

public static function preload_course_contacts(&$courses)

WHERE  ra.contextid ". $sql1." AND ra.roleid ". $sql2." AND u.deleted = :notdeleted

add this to SQL query

AND u.suspended<>1
