[Haskell-cafe] QuickCheck update

[David Feuer]

The latest QuickCheck release was uploaded to Hackage on 2020-11-14.
There have been multiple commits to the master branch since then.
konsumlamm opened an issue on 2023-03-10* requesting a new release.
You responded positively, but there has been no visible progress
towards that goal. Does QuickCheck need additional maintainers?
