Unable to use hspec dependency

[srid]

Just adding hspec to the cabal file is enough to trigger input-output-hk/haskell.nix#1177

As can be seen in CI,

Configuring library for hspec-core-2.9.4..
Error:
    The following packages are broken because other packages they depend on are missing. These broken packages must be rebuilt before they can be used.
installed package ghc-9.2.1 is broken due to missing package exceptions-0.10.4

exceptions is already listed in nonReinstallablePkgs: https://github.com/Plutonomicon/plutarch/blob/19b5e9b90d9df9492e494be730b2169abcdca386/flake.nix#L177

.. yet it doesn't work, contradicting the suggestion from input-output-hk/haskell.nix#1177

Umm, PEBKAC! I hadn't noticed that modules was defined inside tools.haskell-language-server.
