No Free Deaths: Better keepInventory

• Fixes broken drop_xp_in_full mechanic
  • I'm not certain how I broke this, but it has seemingly been broken since release. To mitigate this kind of issue in the future, part of my testing workflow is now to create a new world for release testing.
• Updated pack format to 1.21.5

This is the same as version 1.1.0 but the file has the correct name. I couldn't live with it incorrectly specifying that it was compatible with versions it doesn't support.

Previous version:

• Added a command to toggle dropping the full amount of XP on death instead of following the vanilla mechanics
  • This isn't enabled by default but can be toggled on/off using /function no_free_deaths:cmd/toggle_drop_xp_in_full
  • I think this isn't as nice as the default since it makes the already small penalty for death even less meaningful
• Dropped support for game versions older than 1.21
  • I maintain these packs for myself, and as my own server has been updated, I didn't see a use for keeping backwards compatibility.
  • Version 1.0.0 isn't going anywhere, it'll keep working for as long as you use it. I haven't found any bugs in it, and will fix it if necessary.
  • If you would like any newer features backported, please let me know!
  • The version in the title of the data pack file is incorrect.

First release! This pack is already being used in my SMP, and has proven itself to be useful.

• Players will respawn at half hunger
• Players will lose XP on death
• Players will lose Curse of Vanishing items on death (requires 1.20.5+)
• Not enabled by default: Players will lose health on respawning
