Fix version_suffix for nighly shark-ai packages in build_packages.yml. (#666)

Tested here:
https://github.com/ScottTodd/shark-ai/actions/runs/12244417956 and
confirmed that the `METADATA` embedded within `shark_ai.*.whl` has
`Requires-Dist: shortfin==3.1.0rc20241209` as expected, compared to the
baseline of `Requires-Dist: shortfin==3.1.0`.

I then also ran
```bash
pip install --pre --find-links https://github.com/ScottTodd/shark-ai/releases/expanded_assets/dev-wheels shark-ai

pip freeze | grep sh
