Ubuntu 22 bindists for the release pipeline

[Kleidukos]

@chreekat kindly offered to make a Ubuntu 22 bindists job for the release pipeline, which would be available for the next major release.

For future release managers (including me), hasufell gives us this very nifty snippet for the ghcup-metadata file:

In case you build bindists for Ubuntu 22, Linux Mint will look something like this:

          Linux_Mint:
            '< 20': *cabal-31020-64-ubuntu18
            '(>= 20 && < 21)': *cabal-31020-64-ubuntu20
            '>= 21': *cabal-31020-64-ubuntu22

Work in progress patch is https://gitlab.haskell.org/haskell/cabal/-/commits/b/new-ci-images

[chreekat]

Progress continues. Nearly done with step 1, which is to build all previous platforms with the new version of ci-images. Now just looking at a linker error on Windows; everything else builds.

[chreekat]

The linker errors on Windows went away when I changed the boot cabal-install version to 3.8.1.0. The boot version used to be 3.6.2.0. Is this an acceptable change?

If that helps, let's do it. I think we were just following "if it ain't broke, don't fix it".

29 platforms successfully built here, including Ubuntu 22: https://gitlab.haskell.org/haskell/cabal/-/pipelines/87868

With so many platforms, I'd like to build some way to test the bindists on vanilla Docker images e.g. ubuntu:22.04 before I'd feel confident adding all of them to the release. Isn't there already a ticket somewhere about adding tests to the release pipeline?

Yes: #8044
