Craft Me Chainmail Armor

• Updated recipe keys to reflet changes made in 1.21.2
• Updated recipe component types to reflect changes made in 1.21.2
• Bumped the datapack format

Know issue: Installing CMCA can cause some issues with Roughly Enough Items (REI) mod (tested on 1.21.3 with REI 17.0.789), as it might stop showing chainmail armor and have problems to find the recipe. Although, all datapack's features works perfectly fine, so it's the error on the REI side.
