Zombified piglin anger sounds break under certain circumstances

Zombified piglins now sound angry at the correct pitch in 1.16 Pre-release 6, but at the moment they get provoked, they make a broken anger sound. Unlike the proper sound added in 1.16 Pre-release 6, this broken high pitched sound doesn't change when a baby zombified piglin makes it, never randomly changes pitch, and can overlap with the new anger sounds added in 1.16 Pre-release 6.

To reproduce, spawn a group of zombified piglins. Punch one and notice they sound too high pitched, then proceed being angry at the correct pitch.
