Subject: [PATCH] Fix concurrenct access to lookups field in RegistryOps
The concurrent access occurs on the Netty IO threads when
serializing packets. Thus, it seems it was an oversight of
the implementator of this function as there are typically
more than one Netty IO thread.
Fixes https://github.com/PaperMC/Folia/issues/11
