fix: rename publish workflow to match PyPI trusted publishing (#181)

* fix: rename publish workflow to match PyPI trusted publishing config

PyPI trusted publishing is configured to trust:
  Workflow: publish-pip.yml

But the actual workflow was named:
  publish-packages.yml

This caused publishing to fail with:
  "Publisher with matching claims was not found"

Renamed workflow file to match the PyPI configuration.
