Very Simple Gravestones

• Fixed breaking changes from 1.21.5
• Refactored several tags, scores, and data fields to better conform to common datapack standards (Smithed and Global conventions), and added the Global standard Datapack Info advancement
• Added an Uninstall function to be run before fully uninstalling the pack
• Exploited the "entity_hurt_player" bug so death-tracking no longer requires ticking commands
• Stored item data is now saved to the Interaction's "data" field, removing the need for an extra Marker

Be Warned: This version of the pack will NOT be cross-compatible with previous versions. If you're upgrading your server that already had this pack installed, you must fully remove every grave entity in the old version before doing so.
