Fixed invader version for NeoForge 1.21.1 / Apotheosis 8.8.0 / Ancient Reforging 1.8.5.

Natural Apotheosis Invaders are restored to the stock invader registry/data structure, with only their existing Uncommon/Rare/Epic/Mythic stats rebalanced. The previous pack incorrectly inserted ancientreforging:ancient into Apotheosis invader files, which could prevent the invader data from loading.

Ancient Invaders from Ancient Reforging are balanced in data/ancientreforging/apothic_invaders/the_end instead. Ancient Reforging supplies Ancient End invaders in the End; Ancient is not added as a natural Apotheosis Overworld invader tier.

The rest of the combat/affix/flight blacklist balance from the prior pack is preserved.
