Make repo public for provenance

[jwulf]

We can't get provenance on publish with the repo private.

I will disable provenance for now in release.yml and add a note.

When we're ready to make the repo public, we can re-enable provenance.

 'npm error 422 Unprocessable Entity - PUT https://registry.npmjs.org/@camunda8%2fcli - Error verifying sigstore provenance bundle: Unsupported GitHub Actions source repository visibility: "internal". Only public source repositories are supported when publishing with provenance.\n'
