Milking a mooshroom for stew still plays armor equip sound/shows Gear equips subtitle

MC-97507 was said to be fixed in 20w21a, but this action still plays the sound and shows the subtitle.

While this is mentioned under MC-98316, it probably shouldn't be, as this sound event isn't actually intended to be used by the bowl/mooshroom and is instead the product of a bug. Also note that the armor equipping generic sound plays alongside the milking sound, and not instead of it, which would imply that it used said sound intentionally - the subtitles show both the intended milking subtitle and the incorrect gear subtitle.

Relates to MC-185274
