Regenerative Coma it doesn't work anymore if you have TRAIT_NOSOFTCRIT trait. (#89072)

## About The Pull Request

This is a small change in the symptom of regenerative coma, which I made
so that it would not block other treatment methods in critical condition
due to the insane rate at which self-made viruses spread during contact
transfer. This results in the almost ubiquity of this symptom, which
strongly affects your game, which is very difficult to notice if you are
not a doctor. Very often, this symptom spoils the miners' game, which
leads to idiotic accidental deaths when you use a luxury pen before a
fight and expect that you will be able to fight from a critical
condition, but fall asleep in battle due to an accidentally acquired
virus.

(Or to put it briefly, the TRAIT_NOSOFTCRIT trait (for example,
penthrite gives it) now blocks falling into a regenerative coma.)
## Why It's Good For The Game
There will be no more stupid, pointless and difficult-to-control lapses
into a regenerative coma when you don't need it and you can continue to
live without it.
