[MIRROR] Atmos resin can cool the floor down directly. (#1915)

* Atmos resin can cool the floor down directly. (#82553)

## About The Pull Request
Makes atmos resin set the floor's temperature to 293.15 Kelvin.
## Why It's Good For The Game
The floor can heat the air up. If someone were to extinguish a tritium
fire or something ridiculous with halon, then an awkward situation will
arise where the halon cools the air down, but when someone breaks the
resin open, the floor heats the air back up, triggering the resin to
spawn again and again, which can cause quite awkward problems.
## Changelog
