All configs now use BoostedYAML's objects and methods instead of Bukkit's. They are very similar, so this shouldn't be too confusing of a change on the dev side of things.
Moved FileUtil out of the addons package and added FileUtil#loadFileOrResource.
Removed all Xmas 2022 configs and code.
Fixed an NPE in the Names class.
Removed the custom config updater, as BoostedYAML handles it better.
Added config-version to multiple configs so they can work with BoostedYAML's config updater.
Fixes an NPE in the Fish#checkMessage method.
Adds FishUtils#getSkullFromUUID for use in ItemFactory instead of using API. API was throwing errors on my 1.21 server.
