Hardcore Revival

- Added `/knockout` command to instantly knockout a player
- Fixed knockout screen opening even if `allowAcceptingFate` is `false`
- Shogi Support: Added `hardcorerevival:can_revive` rule (and `hardcorerevival:can_be_revived` rule)
  - This feature requires [Shogi](https://www.curseforge.com/minecraft/mc-mods/shogi) to be installed. It will be ignored if Shogi is not present.
  - For example, a rule like `{ "hardcorerevival:can_revive": "item_cost('minecraft:golden_apple')" }` in `config/hardcorerevival.rules.json` can be used to make revival cost a Golden Apple.
  - The complete [Shogi effect catalog](https://shogi.twelveiterations.com/guides/effects) can be used.
- Shogi Support: Added `hardcorerevival:revived` rule
  - This feature requires [Shogi](https://www.curseforge.com/minecraft/mc-mods/shogi) to be installed. It will be ignored if Shogi is not present.
  - You can use this rule to fully customize what happens after a player is revived.
  - This rule overrides default behavior (like the configured hunger values and status effects) if specified.

- Added `hardcorerevival:bypasses_knockout` damage type tag as an alternative to the `instantDeathSources` config option
- Fixed instant death sources not bypassing damage damage protection while knocked out
- Fixed `rescueRespawnFoodLevel` increasing food above what it was before instead of only maxing food out at that level
