The "pig_big_eat" sounds aren't used

26.1 Snapshot 7 introduced lots of new sounds. Among these, it introduced pig_big_eat1 and pig_big_eat2 which are however unused.

Steps to reproduce the issue:

1. Summon a “big” pig

2. Feed them

3. Listen

Expected result:

• Feeding “big” pigs should produce one of these sounds.

Actual result:

• Feeding “big” pigs doesn’t produce any sound.

• Playing these sounds using the /playsound command causes the subtitle “subtitle.pig.big.eat” to show up instead of an actual subtitle.
