Give PermissionsEX a burial at sea

The plugin is discontinued (has been for a while.)
There are no known builds for 1.13.2 or 1.14.1. While the plugin may work on those versions, administrators are encouraged to phase it out in favor of either [LuckPerms](https://github.com/Lucko/LuckPerms) or [GroupManager](https://github.com/GroupManager/GroupManager)
