"Missing sound for event: minecraft:block.grindstone.use"

The summary shows the warning printed in console while the game loads. When actually playing the game, the sound doesn't play.

How to reproduce:

1. Boot up the game and look through the console/game log, and notice the game warning saying that minecraft:block.grindstone.use is missing
2. Load a world and repair an item using a grindstone

This is especially problematic because there is a subtitle for this sound that is thus never displayed due to this sound not playing: "Grindstone used".
