Menderman

## Changes - Modified the logic for the durability gained when repairing items. - Items now repair based on the current damage value rather than the maximum value. - `current_damage - ceil(max_damage / max_materials) * material_count` - All Spears now have a repair requirements component. ## Bugfixes - Fixed Menderman game rules not being data fixed to the new 1.21.11 game rule format. - Fixed game rule value changes not updating the Anvil GUI's information on clients. - Fixed JEI recipes being misplaced. - Fixed item combining not being modified within JEI. - Fixed the ability to repair at a lower result than you started with in situations where a material repairs less than the item to repair's current durability.
