Rename "pc" edition to "java" #26
Description
Even though in the source minecraft-data repo, the java edition is called "pc" edition, this is misleading and not many people know it under this name. For us, it would make more sense to refer to it as the java edition within the wrapper, for user familiarity and just use pc when loading the data internally within the lib.
This should be as simple as changing the Edition enum and renaming the PC variant to JAVA variant, but leaving "pc" as the value. This would be a breaking change though. We could consider deprecating, but because the lib is still in very early stages, I don't think it's necessary, especially if this is done alongside #23 , which will also be a breaking change without deprecations.
