v4.6.5

• Added getter methods to retrieve menu listener and menu inventory close listener
  Added InvMenu::getListener(), InvMenu::getInventoryCloseListener().
  This allows developers to retrieve the current listener, extend its behavior, and then re-set it.
  This provides more flexibility in chaining or extending listener functionalities without losing the original behavior.

  $listener = $menu->getInventoryCloseListener();
  $menu->setInventoryCloseListener(function(Player $player, Inventory $inventory) use($listener) : void{
  	$listener($player, $inventory);
  	// place additional inventory close checks here
  });
