BodyHealth - Locational Health & Damage

Changed Assembled resource packs now have their own output folder and the existing packaging process of BetterHud's assets to a usable resource pack has been updated to:
...fully support all versions from 1.21 upwards (no more red highlighted, outdated packs)
...make it a little more presentable by reworking the pack's description and adding sort of a gradient
...allow customizing the filenames of generated resource packs
