Removed slot check from removeWeaponAmmoItem event

[GoldO-dev]

Removed the or not item.slot from the if and removed the item.slot from the removeItem function. Because it is pointless

Describe Pull request I have removed the slot check from the weapons:server:removeWeaponAmmoItem event because i see no reason why it is there, it just makes it hard for people that want to use the event to remove the item, since you need to give it the itemData from the inventory and not QBCore.Shared.Items
