Minestom 26.1

The 26.1 branch has now been merged, thanks to all who tested and contributed to it!

New in Minecraft

Added world clocks and clock time markers
- These allow multiple time definitions across worlds (eg overworld vs end time) and separate control of each.
- Minestom loads the vanilla clocks by default.
Vanilla gamerules are now strongly typed in GameRule.
- The client now may request and send back gamerule values via the new operator-only in-menu gamerule editor.
Added cat, chicken, cow, pig sound variants (and their associated dynamic registries)
