Wisdom Cows contain unusual milk (#82269)

## About The Pull Request

Wisdom Cows can now be milked for a random reagent (excepting the
randomly generated reagent blacklist).
Also I changed it to say `you milk the cow` instead of `you milk the
udder` because the latter is stupid.

## Why It's Good For The Game

My experience is that people totally ignore this event when it occurs,
which is _fine_ when we have so many events and they don't all need to
be high impact but I think someone discovering that you can milk the cow
for cognac or meth or something could add something to a round.
I want people to bicker over ownership of the cow, basically.

If the reagent is annoying you can simply speak to the cow to receive
its wisdom and it will disappear.

## Changelog

🆑
add: Wise cows produce surprising milk.
spellcheck: You now milk the owner of an udder, not the udder.
