New ghc-events from 9.4 should also work

I am wondering if the upper bound versioning check is being too strict.

@hellwolf: hi! I can see in CI log that old versions of gtk and cairo are picked. Could you check if bumping bounds on the following packages helps?

I will take another stab this week. I think in nix haskellPackage set, it's broken even for 9.2 atm.

Any updates on this? Would be great to have 9.4 support.
