Minecraft added a feature where you could remove components when giving items, by adding a "!" prefix to the component. This appears to not work on Spigot

Test Commands:
`/give ShaneBee minecraft:diamond_axe`
`/give ShaneBee minecraft:diamond_axe[!minecraft:attribute_modifiers]`

You will notice both items say "9 components" and the second item still has the attribute modifiers.
I tested this in vanilla and can confirm it works in vanilla (the component gets removed in vanilla)
