Chocolate 1.2.0-1.16.4

Added a new vanilla bugfix:

• Fixes MC-197860 : When removing a datapack dimension, this can cause vanilla dimensions to fail to be deserialized from json, and then removed. This results in the permanent deletion of the Nether and End biomes. The root cause is a bug in Data Fixer Upper. However, due to the low likelihood of that getting resolved for 1.16, it is fixed in Chocolate by redirecting the codec construction to use a modified version. Thus, when removing custom dimensions, only the ones actually being removed will be deleted from the save, and all other dimensions will still exist.
