[PATCH 0/6] ci: speed-up the Windows parts of our GitHub workflow

This patch series upgrades to newer versions of a couple GitHub Actions we use, and also streamlines the Windows jobs using the relatively new setup-git-for-windows-sdk Action [https://github.com/marketplace/actions/setup-git-for-windows-sdk] (Git for Windows is running with this Action for a while now, getting all the kinks out).

This patch series should also address the problem where seen was pushed so rapidly that the windows-test jobs failed because they no longer checked out the identical revision as the windows-build job.

Dennis Ameling (1):
  ci(vs-build): build with NO_GETTEXT

Johannes Schindelin (5):
  ci: use the new GitHub Action to download git-sdk-64-minimal
  ci (vs-build): use `cmd` to copy the DLLs, not `powershell`
  ci: upgrade to using actions/{up,down}load-artifacts v2
  ci(windows): transfer also the Git-tracked files to the test jobs
  ci: accelerate the checkout
