chore: Configure Renovate (#659)

## 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: excludePackageNames: excludePackageNames should be inside a
`packageRule` only


Once you have resolved this problem (in this onboarding branch),
Renovate will return to providing you with a preview of your
repository's configuration.
