Fix npm publish for scoped package releases

[Copilot]

The publish-npm GitHub Actions job was failing during release publishing for @veryfi/veryfi-sdk. The workflow reached npm publish, but the publish request for the scoped package was not being sent with explicit public access.

• Root cause

  • publish-npm used a plain npm publish for a scoped package.
  • npm requires explicit public access for publishing a public scoped package.

• Workflow change

  • Updated the release publish step in .github/workflows/npm-publish.yml to publish with public access.

• Resulting behavior

  • Keeps the existing trusted publishing/OIDC flow unchanged.
  • Ensures npm treats the release as a public publish for @veryfi/veryfi-sdk.

- run: npm publish --access public
