Adds an ion storm law that affects the humanity status of station pets (#83527)

## About The Pull Request
Adds a few laws that basically do this:

Has a chance to select a concept that is related to other lawsets, just
in case.

## Why It's Good For The Game
I think it is funny when the AI has to care about the station pets. I
have added the AI law "POLY IS HUMAN" in the past to relative hilarity,
especially when Poly decides to give the AI an order. The other pets
aren't likely to do this, but it's still cute to make the AI care about
the existence of lower lifeforms.

## Changelog

station pets.
