[Feature] Add `ItemLinkEvent`

[TheosisOfficial]

An ItemLinkEvent in the API that fires whenever an item is linked in the chat by a player that exposes the associated Component and ItemStack would be great. My server's players would like to see quantities in item links, and also clickable shulker boxes, so their contents can be previewed in a GUI. These features are probably out of CarbonChat's scope, but I would love to implement them into my own plugin for my server.

EDIT: For every item link, the event should fire. So, if a single chat message contains 3 item links, the event should fire 3 times, once for each link.
