Support GHC-9.8.1

[TeofilC]

Adds support for GHC 9.8.1.

This depends on this MR:

• Support GHC-9.8.1 haskell/ghc-events#102

Looks good! But I am a bit surprised that the CI for 9.8.1 already runs through: If I understood correctly the released version of ghc-events still has a base upper-bound of <0.19 🤔 , so it should only run through once a new ghc-events version is available.

That's because I've also temporarily added an allow-newer pragma to the cabal.project until a new version/revision of ghc-events is released.

Ah, I saw that line but I guess that I misunderstood the semantics of allow-newer. I thought that this only allows to pick a version of ghc-events that is greater than the upper bound that the cabal file allows.

Do you want to merge this now or should we wait for a new release of ghc-events?

[TeofilC]

Yeah I find that confusing too. I think if I had it without the :* then it would be what you mention (IIRC).

It's up to you, but my preference is to wait.

[TeofilC]

This is unblocked now. I've removed the allow-newer and it should be good to go

Thanks!
