fix libcudf wheel publishing, make package-type explicit in wheel pub…

…lishing (#16650)

Follow-up to #15483.

Contributes to rapidsai/build-planning#33

Wheel publishing for `libcudf` is failing like this:

```text
Error:  File "./dist/*.whl" does not exist
```

([build link](https://github.com/rapidsai/cudf/actions/runs/10528569930/job/29176811683))

Because the `package-type` was not set to `cpp` in the `wheels-publish` CI workflow, and that workflow defaults to `python`. ([shared-workflows code link](https://github.com/rapidsai/shared-workflows/blob/157e9824e6e2181fca9aa5c4bea4defd4cc322b0/.github/workflows/wheels-publish.yaml#L23-L26)).

This fixes that, and makes that choice explicit for all wheel publishing jobs.
