Respawn Anchor ambient sound doesn't play

The respawn anchor ambient sound that sounds almost like the portal doesn't play at all. This bug is caused by the missing respawn_anchor.ambient line on the "individual_event_sounds" component in the sounds.json file. Here's the JSON line to add to fix this problem:

"respawn_anchor.ambient" : {
            "pitch" : [ 0.80, 1.20 ],
            "sound" : "respawn_anchor.ambient",
            "volume" : 1.0
         }

Step to Reproduce
1. Fill the respawn anchor with glowstone (max. 4).
2. Listen.

Heard Result
There is no ambient sound from the respawn anchor

Expected Result
It should play the ambient sound when you're close to the respawn anchor.

Do note that this sound is already in the files, it just missing the directory to play it.
