Fix runner label windows-2022 (#18)

The windows-latest runners no longer ships with the Visual Studio 17 2022 generator, which breaks the Windows CI build. Pin the runner to windows-2022 to restore compatibility.

The winget package manager is not available on windows-2022 — download and install mosquitto via run instead.
