ci: Migrate to Windows Server 2022

Per actions/runner-images#4856,
`windows-latest` will default to `windows-2022` soon (not later than
March, 6). Since it seems like we still run on `windows-2019`, force the
migration by specifying `windows-2022` explicitly.

Since actions/runner-images#5050 is
merged, this should fix the failing Web tests on mismatched Chrome and
chromedriver versions.

TODO: Once `windows-latest` defaults to `windows-2022` (again, March, 6),
change back to `windows-latest`.
