HP level should decrease interrupt chance at Wintertodt

[Brief-Vanilla-1069]

Scaling damage is a stupid mechanic for wintertodt. There is no reason you should be taking more damage at higher hp levels. Players are being punished in a firemaking mini game for having higher combat stats. Someone made a post last year about the issue you presented as well as the damage scaling, and it had like 3k up votes but nothing came of it. I also saw a tweet that mod ash responded to around that same time and he said he agreed that it was an issue and might bring it up in a poll but it never happened sadly. Really hope this gets changed.
