chore(workflow): remove unnecessary secret in workflow

This pull request includes a small change to the
`.github/workflows/publish-package.yml` workflow file. The change
removes the `GITHUB_TOKEN` environment variable from the publish step,
likely as it is no longer required for the package publishing process.
