Plugin and Datapack List

Tested by adding the following code to the Paper test-plugin and using runDevServer.

    @EventHandler
    public void onServerListPing(PaperServerListPingEvent event) {
        event.getPlayerSample();
    }

pl
[18:29:46 INFO]: Server Plugins (1):
[18:29:46 INFO]: Paper Plugins:
[18:29:46 INFO]:  - Paper-Test-Plugin

Actions to reproduce (if known)

1. Add the above code to a plugin installed on the server.
2. With one client, navigate in the pause menu to Options -> Online and set Allow Server Listings to OFF. Then join the server.
3. With a second client (not connected to the server), add the server IP to the Multiplayer server list and refresh the server list.
