Add a way to see whats in shulkers in /ah#915

This would help against scamming

you can install a mod or shaderpack to see what’s inside a shulkerbox

it was always added to OneBlock

you just need to click the box to buy and then when this question pops up or this inv with the shulker in the middle and on the right you have the red to cancel and on the left the green to confirm you just click the shulkerbox again and then you can see the shulkerbox contents
