Minecraft 1.21.3 protocol.json. Field "glider" missing in SlotComponent container

[nmalthouse]

Hello,

Within protocol.json for 1.21.3 in the switch definition SlotComponent.data the field glider is missing.
SlotComponent.data is defined as a switch on the type "SlotComponentType" which is a mapper.
The mapper defines a enum value 30: "glider" but doesn't have a corresponding entry in the SlotComponent.data switch.
It should be defined as a void type, many of the other SlotComponent fields are defined as void so I think the omission of this field is a mistake.

I can send a PR if you would like.
Thanks

There are indeed known issues from 1.20.5+. This is being worked on in #948
