ci: disable fail-fast on the windows test matrix

The test-windows job did not set fail-fast, so GitHub Actions defaulted
to fail-fast: true. A single transient failure — often during the
multi-minute SQL Server setup phase — cancelled every other in-progress
and queued sibling job in the windows matrix. Those cancelled jobs would
otherwise have passed, and re-running forced the entire expensive setup
to be redone for all combinations.

The test-linux matrix intentionally keeps fail-fast enabled: those jobs
bootstrap much faster, and because test-windows needs test-linux, a
linux failure should stop the run before the slower windows matrix
starts rather than wasting time on it.
