🎈 Add version 1.21.8 (#53)

* Add version 1.21.8

* send Change branch from 'main' to 'master'

* 🎈 Fix empty ingredients in 1.21.8 recipe generation by using display API correctly (#54)

* Initial plan

* Fix empty ingredients in 1.21.8 by using sl.getIngredients() instead of sl.display()

Co-authored-by: extremeheat <13713600+extremeheat@users.noreply.github.com>

* Update README.md

* Fix 1.21.8 shapeless recipe ingredients by using display API correctly

- Changed from trying to access sl.ingredients field (package-private) to using sl.display() properly
- Extract ingredients from ShapelessCraftingRecipeDisplay using SlotDisplay.resolveForFirstStack()
- Use SlotDisplayContext.fromLevel() to provide proper context for resolving items
- Successfully generates 295 shapeless recipes with proper ingredient arrays instead of empty arrays
- Tested with full data generation run - recipes.json now contains populated ingredients
