Nerfs Ethanol Toxicity To Unathi (#19586)

When I made the recent alcohol toxicity changes to Unathi, I made
ethanol much more toxic to Unathi, because previously it wasn't very
damaging to them unless they drank a lot.

However, when I buffed the toxicity, I forgot to take into account
ethanol scrubber gas. I have discovered, quite rudely, that ethanol
scrubber explosions cause Unathi to instantly go into full 100% organ
damage on every organ, and collapse and die in 60 seconds even with
immediate medical attention. Their organs just all go critical
simultaneously.

This changes things back to the way they were. Unathi and Vaurca will
still vomit up alcohol, but will only take 3 toxin damage per unit of
ethanol instead of 12, which, in hindsight, was quite ridiculous.
