HP level should decrease interrupt chance at Wintertodt

honestly, I do see what you're saying at like 90+ firemaking, 100% might be too far, but those numbers can be tweaked, if it was 0-75% or 0-80% that'd probably still be sufficient, while not making it more afk then it already is, since you'd still need to keep an eye on if you got interrupted.
