AoA3 Improvement Datapack

A datapack made of 1.16.5-3.6.11 version of AoA3 to solve some annoying issues of its gameplay, including:

• Decrese the overly-high Hp values of AoA3 mobs.
• Fix a bug that the guardian doesn't drop biogenic armor.
• Add recipes of rune post to make them survival accessible.
• Add a recipe to allow players to craft poison rune using spider eyes, as AoA3 did after 3.7.7.
• Add a recipe to allow players to craft water rune using ices, making the recipe stackable.
• Move the structures of Mysterium to the ground to be easier to find.
• The rune templars will glow to be easier to find.
