feat: Add support for Minecraft 1.21.11 (Protocol 774)

Add minecraft-data support for version 1.21.11 'Mounts of Mayhem':

New Content:
- 4 new entities (camel_husk, nautilus, parched, zombie_nautilus)
- 1 new mob effect (breath_of_the_nautilus)
- 16 new items (spears, nautilus armor, spawn eggs)

Files added:
- data/pc/1.21.11/ directory with all data files
- dataPaths.json updated with 1.21.11 entry

Note: This PR focuses only on 1.21.11 as 1.21.9/1.21.10 support was
already merged via PR PrismarineJS#1096.
