Better Craftables

I wasn't going to release this so soon after v1.2.3, but I felt motivated to do so. Enjoy!

Changelog:

• Added cheaper Smithing Template duplication recipes
  • Costs 3 Diamonds instead of 7
  • Works with all Smithing Templates, including the Netherite Upgrade Template
  • 
• License is now included in the data pack ZIP file

This version is compatible with Minecraft Java 1.20 and 1.20.1.
