Not compatible with aeson 2.2.0.0
In https://github.com/morpheusgraphql/morpheus-graphql/issues/824#issuecomment-1519180163, there's a deprecation warning that module Data.Aeson.Internal is deprecated.
When trying to build an empty Cabal project with Cabal 3.10.1.0, GHC 9.6.2, and this build-depends:
build-depends:
base ^>=4.18.0.0,
morpheus-graphql ^>=0.27.3
I get these errors:
src/Data/Morpheus/App/MapAPI.hs:14:1: error:
Could not find module ‘Data.Aeson.Internal’
Perhaps you meant
Data.Aeson.Internal.TH
Data.Aeson.Internal.TH
Data.Set.Internal (from containers-0.6.7)
Use -v (or `:set -v` in ghci) to see a list of the files searched for.

14 | import Data.Aeson.Internal
| ^^^^^^^^^^^^^^^^^^^^^^^^^^...
src/Data/Morpheus/App/MapAPI.hs:18:1: error:
Could not load module ‘Data.Aeson.Parser’
It is a member of the hidden package ‘attoparsec-aeson-2.2.0.0’.
Perhaps you need to add ‘attoparsec-aeson’ to the build-depends in your .cabal file.
Use -v (or `:set -v` in ghci) to see a list of the files searched for.

It seems like aeson-2.2.0.0 has removed the deprecated modules.
I wouldn't mind sending in a PR to fix this; however, I'm new to Haskell ecosystem, so I'm not sure if me modifying this library to be compatible with the latest version of Aeson will break previous versions of morpheus-graphql.
Thanks for your work on this library. I'd be happy to contribute this fix if necessary.
In the meantime, I was able to build the project by adding aeson == 2.1.2.1 to my build-depends.
Based on the aeson changelog, Data.Aeson.Internal was removed in 2.2.0.0..
I think the PR would be pretty trivial - just replacing Data.Aeson.Internal with Data.Aeson.Types in morpheus-graphql-app.
@thosakwe I'm not a maintainer of morpheus, but I think you should create a PR for it. If accepted, they can make a new release with an updated version number with the change. Users can depend on the current version to avoid any breaking changes.
