The translation key used for the subtitles when the sound "alexscaves:caniac_swing" is played is "alexscaves.sound.subtitle.caniac_attack" instead of "alexscaves.sound.subtitle.caniac_swing."

Reproduce:

1. Enable subtitles in the settings.
2. Enter the command /playsound alexscaves:caniac_swing master @s in the chat.
