Bug Description

The item data in chat hover events on 1.20.6 servers are not properly translated to 1.20.4 clients so item data like custom names, enchantments, attributes, and others are not visible to 1.20. clients.

Steps to Reproduce

Start a server with 1.20.6
Join server with a 1.20.4 client
Execute command tellraw @a {"text":"Hover me!","hoverEvent":{"action":"show_item","contents":{"id":"cake","count":1, "components":{"cu stom_name":"{'text':'Special Cake Name',color:'yellow'}"}}}}
The 1.20.4 client hovers over the chat message and only sees a default cake item
A 1.20.6 client client sees a cake with a yellow custom name "Special Cake name"

Expected Behavior

The 1.20.4 client should see the "Special Cake Name" custom name on the cake item when hovering over the chat message.
