Subject: [PATCH] Fix release workflow: checkout submodules for wheel and sdist
 builds
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The build-wheels and source-distribution jobs used actions/checkout
without submodules, so src/ion-c/ was empty and CMake failed with
"does not contain a CMakeLists.txt file".

Also remove the PyPI verification step from source-distribution — it
tried to pip install from PyPI before anything was published there
(upload-wheels runs later), so it always failed.
