(Java) Hide the new multiplayer managements from the escape menus

When on the main MineCraft home menu or escape menu, the buttons for the new multiplayer features are in the way a little, and may disrupt players muscle memory. the features are definitely needed, (i don't know how other people feel about the features) but i think it's better to place them at the bottom or in the options menu.

thanks

i don't know if this is supposed to be in the gameplay topic or accessibility topic, my bad
