The Bug:

The "Allow Server Listings" option is ignored for realms.

24w21a introduced a feature where online players would be displayed within the realm list when they're on a said realm, however, the "Allow Server Listings" option is taken into consideration here. When a player has their "Allow Server Listings" option set to "OFF", their player name and skin will still be displayed within the realms menu on the said realm for other players.

Steps to Reproduce:

1. Have a player join your realm and have them navigate to the online options menu and set their "Allow Server Listings" option to "OFF".
2. Navigate to the realms menu and hover over the player head that lists the online players.

Observed Behavior:

The "Allow Server Listings" option is ignored for realms.

Expected Behavior:

The "Allow Server Listings" would work for realms.
