Added immersive engineering crates to the blacklisted item in the serverconfig

#Common configuration settings [common] #A list of items that are not allowed inside a backpack. Note: It is recommended to ban items that have an inventory as this will create large NBT data and potentially crash the server! bannedItems = ["<immersiveengineering:crate>"]

But I can still put IE crates inside my backpack. Log states:

[13:26:31] [Server thread/WARN]: Configuration file C:\Users\damie\curseforge\minecraft\Instances\Immersive Engineering 1.16.5\saves\New World (4)\serverconfig\backpacked-server.toml is not correct. Correcting

I've tried with other syntax (eg without the quote marks) but it crashes instead so I reckon I've got the correct NBT tag syntax?

Not a bug.
bannedItems = ["immersiveengineering:crate"] is the correct syntax.
