Temporary bees animate on death and no longer produce corpses (#81714)

## About The Pull Request

I requested this as a change on the Hive Head PR but Ghommie didn't
notice and merged it anyway so I had to do it myself instead of forcing
the underclass to do it for me 😔

Anyway now bees created by the "beesplosion" reaction and by the Hive
Head changeling power no longer produce corpses, and have a death
animation.

## Why It's Good For The Game

It looks better.
It was weird that the bees would create corpses if killed but not if
they expired.
