Changes

Correctly datagen the milk containers tag and remove two non-genned ones

Remove cauldron recipe registrations

Serializers are no longer registered as they won't work anyways, and recipes for ice/fermenting potions have been removed
Still need to remove the relevant recipe logic, not sure yet whether I will do that before or after its replacement
Also ditch a few other cauldron things that no longer work, like dispense cauldron recipe

Config cleanup

Update mantle for new recipe helpers, use newer recipe helper util instead of the old one
Remove unneeded module config in JSON, that config is already checked in the internal predicate for the config
Migrate anything used in recipe loading to common config, server config is too late
Bring back dyed bottle mixing recipes, want to do something more with that later in cauldrons themselves
Remove book keywords for bookshelves, using full tags now
