PotionEnchant

整理配置类，并添加新配置项：

1.可调整战利品表生成终极药水护符的概率

2.可控制装备的药水附魔等级上限（不影响终极药水护符）

3.把通过Forge事件系统实现的独立药水附魔tooltip改为通过mixin实现

Organize configuration classes and add new configuration items:

1. The probability of generating the ultimate potion talisman from the adjustable loot table

2. Can control the upper limit of equipment's potion enchantment level (does not affect the ultimate potion talisman)

3. Change the independent potion enchantment tooltip implemented through the Forge event system to be implemented through mixins
