[FrunoCraft] 200k to 1.2M Creeper Farm

by @FrunoCraft Recomendation Two players are needed, to kill the creeper, either a carpet bot in singleplayer or a buddy on a server Corrections In version 1.21, canisters can no longer be used to expel enemies from a portal, as canisters would simply pass through it. Just close the portal with solid blocks. A small improvement could be to use blocks of different sizes, such as mixing walls and building blocks. But the farm works well in another way
