I verified the the workflows well through https://github.com/python/cpython/actions/runs/11422707050/job/31781018424
This PR separates the task from check_generated_files but for unifying to the single task, we may need full unified devcontainer images to be used at https://github.com/python/cpython-devcontainers

Let's handle it separately.

Since the container python used has something different from Github Action official base image and that is the reason why we should switch to the internal container ?

See: https://discuss.python.org/t/pinning-gnu-autotools-using-the-github-container-registry/47437/29

FYI, The purpose of CI is verification of whether the person generate autoconf properly

So that’s why we have to unify the image to be same.

Thanks. I need this for #125571.

Does that should be backport to 3.13 and 3.12 ?

I think we should backport it, yes. Hugo?

[hugovk]

Yes, it'll be easier to maintain if the three branches are more similar.
