Silly Zombie Sounds

I got bored of the vanilla zombie sounds while using a mob grinder. Zombies now make silly meme sounds. The list of sound bites and credits are in the pack.

Initially made for Java snapshot 25w32a, should support every snapshot/version for a long time.

Currently supports pack_format values 65.1 to 900 (900 is an arbitrary number, but it should keep this pack from breaking for a long time).
