* gitlab ci: Don't install stack

Fixes #9304

* Repair cabal's index state

Fixes #9312

* Expand alpine builds to include i386

Note the use of ghc-9.0.2 for i386-alpine.

Resolves #9347

It is no longer just x86_64.

Use a specific release instead of HEAD.

* Bump ci-images pin

* Combine Debian 10 and 11 in a matrix job

* Add most of the GHC 9.6.1 platforms that fit on the x86_64 runners

* Add centos7

Extends the "configure" logic in .gitlab/ci.sh :(

* Remove platforms unsupported by GHC 9.6.1 or Cabal 3.8.1

* Remove aarch64-linux-deb10

GHCUp fails to run on aarch64-linux-deb10 due to a glibc mismatch.

aarch64-linux-deb11 would work, but there is no GHC release for that
version yet.

* Reset GitLab CI verbosity
