Define custom brewing recipes and provide unique give commands.

Currently defined potions brewing recipes:

• bottle of milk (only used as brewing ingredient) - bucket of milk + empty bottles
• splash milk potion - gunpowder + bottles of milk
• debuff removing only potion - netherite ingot + splash milk potions

Commands:

• /milkpotion <amount>
• /debuffpotion <amount>

TODO:

• balance debuff remover brewing cost
• extract potion recipe creation to be independent of internal methods
• add config option to enable and disable defined potions
