`test_dtrace` fails on Windows Server 2025

Bug report

Bug description:

GitHub Actions is in the process of migrating windows-latest from windows-2022 to windows-2025:

This change will be rolled out over a period of several weeks beginning 2025-09-02 and will complete on 2025-09-30

actions/runner-images#12677

This is causing failures for forks which have already been migrated, for example:

Upstream and my fork are still on 2022, but let's pin to windows-2022 so we can separately investigate and fix for 2025, and then pin to windows-2025.
