feat: add MC 1.21.7/1.21.8 (protocol 772) support

Browse source 
1.21.7 and 1.21.8 share protocol 772. The only registry change from
1.21.6 is one new item (music_disc_lava_chicken). All other palettes
(blocks, entities, packets, entity metadata, structured components)
are unchanged and reuse 1.21.6 versions.

Changes:
- Add MC_1_21_7_Version (772) constant
- Add "1.21.7" / "1.21.8" version mappings in ProtocolHandler
- Add MusicDiscLavaChicken to ItemType enum
- Generate ItemPalette1217 (1416 items) for the new item palette
- Update all version upper-bound checks from MC_1_21_6 to MC_1_21_7
- Update MCHighestVersion to "1.21.8"
