Cleanup and fix CI jobs for Darwin

[avdv]

• Do not invent version number
• Use macos-12 runner images

This fixes the failing CI jobs for Darwin because of the roll-out of switching macos-latest to macos-14 arm64.

Currently, the CI bindist job for GHC 9.8.1 for rules_haskell_test fails with:

Error in fail: rule @//tests/haddock:haddock generates

This also happens for all the renovate PRs.

I'll update the expeted values, but @aherrmann / @ylecornec do you have an idea why the suffix (is this the package id?) of the haskell_haddock outputs changed?

Oh, it's because macos-latest is arm64 now... which should be added / switched to in #1747

github/roadmap#926

Actions workflows using the macos-latest label will incrementally transition from macOS 12 to macOS 14 beginning April 8th 2024 and will conclude before the end of June 2024.
