Building exe:print-api with the latest supported version of GHC

[Kleidukos]

@mmhat Currently as we stand, we provide print-api-$ghc_version and print-api as part of every build job that is specific to an OS and a GHC version:

I would like to suggest that we use the latest GHC version supported to build print for each OS, as a different job. What do you think?

Oh that would be a lot cleaner than the current GH workflow! As I wrote in #16 (comment) I'd prefer that get-tested indicates what the newest tested GHC version is. For your propsal I think it would be enough if there was a --latest flag for get-tested that outputs a matrix with the newest GHC only.
Until that is supported, I think it is fine to hardcode the GHC 9.10.1 release in the proposed job.
