chore(3p/sources): Bump channels & overlays

The main change is that nixpkgs updated to GHC 9.2 and Stackage LTS-20,
so we suffer from a bit of churn.

* //3p/overlays/haskell:

  - use updated dhall-nix patch for hnix 0.16

  - use superrecord fork with fixes for GHC 9.2

  - use graphmod-1.4.5.1 which has support for GHC 9.2

* //users/Profpatsch: relax constraints on base in Haskell pkgs

* //users/Profpatsch/cas-serve: inherit superrecord from 3p

* //users/grfn/xanthous:

  - //3p/overlays/haskell for 8.10.7:

    * Provide missing dependency of binary-orphans. Fix already commited
      upstream as e238c3fdaab710a2ce0135e5a77cd7e6bb023a22, can be
      dropped when channel advances.

    * Downgrade to brick 0.71.1, the latest version xanthous supports.

  - Adjust to generic-arbitrary >= 1.0, providing Arg constraints where
    necessary.

  - Increase constraint-solver-iterations to 6 (default 4), so
    Xanthous.Command and Xanthous.Data can be typechecked.

  - Drop NFData instances for Key and Modifier which have been added to
    vty upstream.
