Subject: [PATCH] Fix uncorrected death check of folia

In the new mc version, mojang changed some checks in A.C.M(AbstractContainerMenu) and there is a new death check of player which will be executed when player dead.But on folia, player entity cannot be discarded unless they disconnected from the server, so there is an obvious bug that when player dead, the logic depend on that dead check will not be executed correctly because the check logic is still asserting the player is alive by checking if the player is discarded, which caused some exploits can save items in the crafting slots(with InventoryTweaks turned on in meteor client) when keepInventory is set to false
