Example for using trusted puclihser uses wrong key

[francescalb]

As you see from here: https://github.com/emmo-repo/EMMOntoPy/actions/runs/11517274255/job/32062083099,
package-dir is not a functioning key.

Valid keys are: ['entryPoint', 'args', 'user', 'password', 'repository-url', 'repository_url', 'packages-dir', 'packages_dir', 'verify-metadata', 'verify_metadata', 'skip-existing', 'skip_existing', 'verbose', 'print-hash', 'print_hash', 'attestations']

The example with the error looks like this:

  - name: Publish to PyPI
    uses: pypa/gh-action-pypi-publish@release/v1
    with:
      # The path to the distribution to upload
      package-dir: my-dists
