fix #58: Let's try haskell-ci

As per usual for anything related to cabal nothing works unless properly massaged. Currently stuck at ghc-9.6.4: could not execute: hspec-discover, which I assume requires another inane configuration line in *.cabal.

Apparently, at least cabal can now use stackage snapshots for dependency resolution using the cabal.project file, e.g.:

packages: .
import: https://www.stackage.org/lts-22.27/cabal.config

(haven't tested yet)

I had to ignore failures in the cabal check step because I'm simply not going to add the upper bounds for my dependencies.
