Update cabal.project.freeze for GHC 9.10.1 update (#3035)

This PR updates the cabal freeze file to reflect the changes to
dependencies after the GHC 9.10.1 stack.yaml update.

@janmasrovira can you check this? The last time I think you updated this
and the freeze file was much smaller for you.

I downloaded the stack2cabal binary from
https://github.com/hasufell/stack2cabal/releases/latest and ran
`stack2cabal` in the root of our repo.

* Fixes #3036
