fix(ci): allow optional secrets in publish-r2 reusable workflow (#563)

When using 'secrets: inherit' in the calling workflow (dev-deploy.yml),
the secrets must be marked as required: false to avoid validation errors.
The secrets are still passed through inherit and will be available at
runtime from the repository/organization settings.
