Adjusts all get_temperature() accesses to compare it to a value (#95236)

## About The Pull Request

``get_temperature()`` returns a value in kelvins, not a boolean. Trying
to treat it as such will result in ***any*** item with a thermal value,
like condensers, being treated as a lighter.

## Why It's Good For The Game

Consistency, allows us to have actually functioning cooling items that
don't act like lighters all the time.
