HuskSync 3.7.3 - Bug fixes

HuskSync 3.7.3 is a small update to address a few issues.

• Updated the Packet-Events hook to support 1.21.4 (please note ProtocolLib still hasn't updated yet and won't work on 1.21.4)
• Fixed PostgreSQL failing to update snapshots in the database, courtesy of @solaluset (#440)

To update, just drag+drop. Compatible with Paper/Fabric for Minecraft 1.20.1, 1.21.1, and 1.21.4.
