Unused textures: goldheart_[0.2].png

The bug

Three unused yellow heart textures have been included in the particles texture folder since 23w12a: goldheart_0.png, goldheart_1.png and goldheart_2.png. They do not appear to be used by the game anywhere and should therefore be removed.

How to fix

Remove these three textures from the game. Either that, or make use of them in the vanilla game.
