[PATCH 0/2] ci(GitHub): mark up compile errors, too

Just like we mark up test failures, it makes sense to mark up compile errors, too.

In a sense, it makes even more sense with compile errors than with test failures because we can link directly to the corresponding source code in the former case (if said code has been touched by the Pull Request, that is). The only downside is that this link currently is kind of misleading if the Pull Request did not even touch the offending source code (such as was the case when a GCC upgrade in Git for Windows' SDK all of a sudden pointed out problems in the source code that had existed for a long time already). We will see how the GitHub Actions engineers will develop this feature further.

This patch series is based on js/ci-github-workflow-markup. Which also serves as an example how this looks like if the offending source code was not touched by the Pull Request: https://github.com/gitgitgadget/git/actions/runs/2461737185 because it still triggers the above-referenced GCC build failure.

Johannes Schindelin (2):
  ci(github): use grouping also in the `win-build` job
  ci(github): also mark up compile errors
