ci: Remove registry-url from setup-node to fix npm trusted publishing

The setup-node action with registry-url creates an .npmrc that sets
NODE_AUTH_TOKEN to the GitHub token, which overrides npm's OIDC
trusted publishing flow. Removing registry-url lets npm handle
authentication via OIDC directly.
