Support GHC 9.6

[chshersh]

The GHC 9.6.1 was released recently and it makes sense to support compilation of iris with the new version of the Haskell compiler.

Steps needed to be done:

• [ ] Increase base upper bound in iris.cabal https://github.com/chshersh/iris/blob/e9b6c25df2bf179dc8d9f32f05c55aa8f7febcce/iris.cabal#L29-L30

• [ ] Update the tested-with field https://github.com/chshersh/iris/blob/e9b6c25df2bf179dc8d9f32f05c55aa8f7febcce/iris.cabal#L19-L23

• [ ] Add new warnings https://github.com/chshersh/iris/blob/e9b6c25df2bf179dc8d9f32f05c55aa8f7febcce/iris.cabal#L55-L56

• [ ] Fix all compilation errors and warnings if any

• [ ] Update CI pipelines

I'd like to tackle this one 😊

[chshersh]

@celsobonutti Sure, go for it 👍🏻

This depends on colourista supporting 9.6, so I’ve created a PR there. Once that’s merged, I’ll do the work for this issue.

@celsobonutti Thanks for the heads-up!

I replaced colourista with pretty-terminal in #118, so iris shouldn't be blocked anymore. Feel free to continue the GHC 9.6. support in this repository 🙂

Oki doki! Thank you!
