Action Required: Fix Renovate Configuration

There is an error with this repository's Renovate configuration that needs to be fixed. As a precaution, Renovate will stop PRs until it is resolved.

Location: `renovate.json`
Error type: The Renovate configuration file contains some invalid settings
Message: Invalid configuration option: node

Start with renovate.json and inspect the configuration around the invalid node option. Validate the file with Renovate's configuration checks; done means the invalid-settings error is gone and Renovate can resume creating pull requests.
