Backport linux32 CI fix from upstream Git (#5145)

The `linux32` jobs are seeing this error:

    Error: This request has been automatically failed because it uses a
    deprecated version of `actions/upload-artifact: v1`. Learn more:

https://github.blog/changelog/2024-02-13-deprecation-notice-v1-and-v2-of-the-artifact-actions/

To maintain CI builds that typically succeed, let's cherry-pick this
into Git for Windows' `main` branch.
