HuskSync 3.7 - Bug fixes, new release system

HuskSync 3.7 makes stability improvements and fixes bugs. This release also introduces a new release model for HuskSync as previously announced, which adds support for Fabric 1.21.1. HuskSync 3.7 supports Spigot/Paper/Fabric 1.20.1 and 1.21.1 (download the right version for your server).

• Changed the way the plugin is published. You must now download the correct JAR for your server's Minecraft version. See the announcement post on Discord for more details.
• Added support for Fabric 1.21.1, courtesy of @hui1601 (#339)
• Added an option to disable automatic DDL operations for servers with locked-down SQL user access, courtesy of @TheCodedOne (#377)
• Added an aftermarket service command which force-upgrades all legacy user data from HuskSync v2
• Users are now locked just prior to their data being updated following an inventory or ender chest command which updates their data
• Attributes are now allow-listed instead of deny-listed.
  • This was done for a number of reasons, but primarily because it's a better config default; in the vast majority of cases users only need a specific set of attributes synced.
  • This prevents various edge-case attributes from being erroneously synced, too
• Fixed item and block statistics not syncing (#362)
• Fixed attributes not syncing when the default values were the same as the user's value due to an oversight, causing users whose attribute values reset from not syncing
• Fixed issues with data rotation when the database mode was set to PostgreSQL (#383)
• Fixed an issue on Paper 1.21.1 with map cursors not being correctly synced
• Fixed an issue Paper 1.21.1 where inventory crafting slots weren't properly cleared for safety during sync

✅ Compatible with: Spigot/Paper/Fabric 1.20.1 and 1.21.1 (download the right version for your server).
