Some Fixes [3.8.1]

This update comes quick after 3.8.0 due to some bugs that prevent loading.
3.8.0 was a pretty big release so please make sure to read the 3.8.0 change log before updating to 3.8.1
I wasn't planning on adding new features to a patch release, but I wanted to get those item components behind the feature flag before too many people started using them.

Caution

Due to API changes/new features in Skript 2.10.x, SkBee now requires Skript 2.10.x+

Warning

ItemComponents are now locked behind item_component experimental feature.
Paper has these listed as experimental and may change anytime, possibly with breaking changes.
Use these item components with caution.
I mean to do this before the release of 3.8.0, but got sidetracked... my bad!

FIXED:

• Fixed a bug where some classes attempt to load on MC versions where they don't exist
• Fixed a loading error with ItemComponent utils causing the plugin to crash on old MC versions

ADDED:

• Added an expression for the potion type of an item
• Added a potion contents component section
• Added a section for applying potion effects/consume effects

CHANGED:

• Changed the structure of the death protection component to use a section for applying consume effects.
• Changed the structure of the consumable component to use a section for applying consume effects.
• ItemComponents are now locked behind item_component experimental feature.
  Paper has these listed as experimental and may change anytime, possibly with breaking changes.
