* 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
