Issue Description
Items in circulation in the world before updating MM to have the ItemUpdater config setting do not append the MYTHIC_ITEM_VERSION: 2 tag, when added to config of the item (even with multiple version changes made)
I have attached a video of an item I received via command after using newest build of MM, MCrucible. In the video I have a stack of older wands that are a blaze_rod item, which the new config changes to a warped_fungus_on_a_stick.
The item from the command updates perfectly, however the items without a MYTHIC_ITEM_VERSION tag present do not change, nor do they acquire this tag after changes are made.
This is not exclusive to items that change type; old items that keep their itemtype but change name or lore also do not update.
