Protocolize not working in Velocity with MC 1.20.3+ clients

[Wirlie]

Description of the problem:

As title says, protocolize is not compatible with Velocity proxy and MC 1.20.3+ clients due a new implementation in the client protocol that requires inventory titles to be serialized as NBT.

Protocolize is aware of this issue (see Exceptionflug/protocolize#211), but unfortunately, Protocolize is unable to fix this issue as of now because there is not way to serialize a component (adventure) to NBT, anyway, adventure is aware of this feature lack (see KyoriPowered/adventure#995).

As of now, I cannot do anything to fix this issue, until adventure introduces a way to serialize a component to NBT and Protocolize brings an update to handle this change.

NOTE: This issue does not affect BungeeCord proxy, only Velocity.

Temporal workaround:

Disable the GUI feature from enhanced-glist configuration if you are affected by this issue.
