BlockEntityType's registry is not synced on 1.18.x, causing desyncs

Since 1.18, Minecraft uses raw BlockEntityType ids in packet for syncing data (BlockEntityUpdateS2CPacket).
Fabric currently doesn't sync these, which can cause desyncs.

Placing PipeBlock, and displaying Block (Entity) update packets, uses wrong BlockEntityType

That’s annoying. At least it’s a trivial fix.
