Make a default-language optional in cabal-version: 3.2

[phadej]

It's essentially always Haskell2010 nowadays.

We can introduce the same Default thing as we did with build-type

👍 / 👎 ?

I've been wanting to do this as well; the only thing we need however is to make sure that there's a way to not send any -XHaskell2010 or -XHaskell98 at all to GHC (e.g. via an empty default-language: ?), i.e. to explicitly select GHC's default mode... or maybe we don't need that?

Is there a way to not-send any -XHaskell* nowadays? Omitting default-language field generates an error, is that wrong?
