CI: validate.yml: remove the git workaround that started failing on Windows

[ulysses4ever]

I wanna see if this is still needed.

The failure looks like this:

Run git config --global protocol.file.allow always
error: could not lock config file C:/msys64/home/runneradmin/.gitconfig: No such file or directory
Error: Process completed with exit code 255.

e.g. https://github.com/haskell/cabal/actions/runs/16415578333/job/46397611829

Template B: This PR does not modify behaviour or interface

E.g. the PR only touches documentation or tests, does refactorings, etc.

Include the following checklist in your PR:

• Patches conform to the coding conventions.
• Is this a PR that fixes CI? If so, it will need to be backported to older cabal release branches (ask maintainers for directions).

after all validate tests were smooshed into one github action step, I am positively unable to read the logs. Is anyone able to point me to the actual error message?

I'm confused, when did this change you mentioned happen? The only one I remember added folding output sections.

[ulysses4ever]

that one, yes

[ulysses4ever]

I don't understand where the failure is but logically, this workaround seems to be effective still. Closing…

[geekosaur]

Perhaps we should only skip it on Windows?

[ulysses4ever]

Good point! I don't currently have time to try it 😕
