Add FsCheck examples to shrinking challenge

[jlink]

There’s a repository targeted at comparing shrinking behaviour of various PBT libraries: https://github.com/jlink/shrinking-challenge

Would be great to have FsCheck therein. We’re happy to take PRs.

Interesting! Probably won't have time myself, but happy to provide support.

I’m yet to write my first line of f# so maybe there are other folks who might want to pick the topic up as a challenge (pun intended).

I did a few here: jlink/shrinking-challenge#18

Quite fun, some good property-based testing exercises in there as well.
