Handful of fixes

[Apollounknowndev]

• Fix liquid_settings and override_liquid_settings being required
• Fix random_group pool alias binding being broken on 1.20.3 and above
• Remove the ability to inline structure sets in exclusion_zones

The ability to reference predicate files in enchantment effect conditions also needs to be removed but that seems a bit too complex for me to do :P
