I modified a random file (Lib/test/test_dtrace.py) to trigger the Windows CIs. I will revert this TEST change once I will have the confirmation that the Windows CIs pass.

This change leaves .azure-pipelines/ci.yml unchanged, it still contains:

- job: Windows_CI_Tests
  ...
  pool:
    vmImage: windows-2022

I propose updating .azure-pipelines/ci.yml in a separated change.

See also #144679 : we might wait and upgrade directly to windows-2025-vs2026 image.

The PR is now ready for review.

I got the confirmation that Windows CI jobs pass successfully with this change, so I reverted the TEST change to trigger these jobs.
