Better Bundle [Data Pack]

🔷General

• Updated to 1.20.3 / 1.20.4

✨Additions

• Added particle and sound effects when:
  • Transferring items from a chest to a bundle
  • Quickly dropping items from a bundle into a chest
• Trying to quickly drop the content of a bundle inside a chest that's not empty now produces an error

💫Changes

• The advancement 'Is this a Shulker Box?' is now granted upon the player picking up a filled bundle (as a result of the transfer operation), rather then when the player interact with a chest while holding a bundle
  • This change now prevents the player from obtaining the advancement if the items transfer fails

🔧Improvements

• Overall improvements to the Data Pack structure and understandability
• Merged all the separate directories into the main one

🐛Fixes

• Fixed an issue where quickly dropping the content of a bundle into a chest that already had items would result in those items being erased permanently
