Enderman sounds are misspelled within index files

Some info

• This bug relates to MC-115987, and was not fully fixed. That bug was not specifically assigned/fixed by a developer; it was fixed indirectly. Any commands and code within the .jar file have been fixed, but the index file was not fixed.

• There are 17 instances of 'endermen' in the index file, and no instances of 'enderman' in the index file.

• This report should be categorized as Text.

The bug

Within the index file (1.16.json), sounds by endermen are incorrectly pluralized. For example:

"minecraft/sounds/mob/endermen/hit2.ogg": {"hash": "cf60aefd0b742c3fa15e808c1a0c33aebd534cc5", "size": 6491}

This is inconsistent with other entity sounds, as they are not pluralized. For example:

"minecraft/sounds/mob/zoglin/angry2.ogg": {"hash": "4b8537a426378b7c17bebcbd6604728d38f0c6d3", "size": 30496}

"minecraft/sounds/mob/enderdragon/end.ogg": {"hash": "53cc1890ebea833d3964c7dd1c90676650e34404", "size": 257102}

The expected enderman sound should be labeled:

"minecraft/sounds/mob/enderman/hit2.ogg": {"hash": "cf60aefd0b742c3fa15e808c1a0c33aebd534cc5", "size": 6491}

Notice that 'endermen' has been changed to 'enderman' to be consistent with other sounds.

How to reproduce

1. Locate and open your Minecraft folder (exact directory may change based on your operating system, look here if you're not quite sure how to get there)

2. Go to: assets >> indexes >> 1.16.json and open the file with a text editor (TextEdit, Notepad, etc.)

3. Find in document: "endermen" and notice that all 17 cases are incorrectly pluralized.
