Building iron golems does not create snowball particles

Relates to MC-258347.

From their introduction up to 12w17a, when built, iron golems would create a burst of snowball particles around them. This stopped happening in 12w18a due to MC-10369. While said ticket was said to be fixed in 19w14a, building iron golems still no longer creates these particles (any created are a result of MC-123338 and are obviously not snowball particles).
