ci/windows: fix zink msvc build-rules

When I added the build-rules for zink to the windows build, I
accidentally added it to .windows-test-rules instead of
.windows-build-rules. This seems to trigger a build-error if we trigger
*just* a test due to a zink-change, but not a build.

Hopefully this fixes the problems Mike has had with Zink CI recently.
