elmPackages.elm: don't check aeson

[mpscholten]

Checking aeson fails as it depends on nothunks < 0.3, but we provide nothunks >= 0.3. Jailbreaking doesn't work in this context, so I disabled the tests instead.

I've also created an upstream fix via haskell/aeson#1129

So this seems to be because of this:

https://github.com/haskell/aeson/blob/85c2da59d68953e48720e18f632689f385237e58/aeson.cabal#L242-L243

I think what we should do is to add the missing nothunks dependency (in the correct version) to configuration-ghc-9.2.x.nix, configuration-ghc-9.4.x.nix, configuration-ghc-9.6.x.nix. Alternatively, we could disable the checks there.

In any case, this same problem appears in haskell.packages.ghc96.aeson etc., so we should fix it at that level.

WDYT?

Running the test suite would be ideal, but I suspect providing nothunks in the correct versions would mean downgrading it globally since e.g. unordered-containers depends on nothunks which in turn is needed by aeson. I'm not sure what cabal will do actually if we disable the inconsistent dependency check when building a test suite with such a package…
