Fix release workflow artifact pattern mismatch

The release job was failing because it was looking for artifacts with pattern 'wheels-*'
but the build job uploads an artifact named 'wheels'. This caused 0 artifacts to be
downloaded, resulting in 'No files found to publish' error during PyPI upload.

Changes:
- Update artifact download pattern from 'wheels-*' to 'wheels' to match actual artifact name
- This fixes the configuration race condition between build and release jobs

Fixes the v0.56.1 release failure where PyPI upload failed due to missing artifacts.
