need more examples of valid configurations

https://github.com/aws/aws-cdk/discussions/31209

The schema for feature flags is now available but it's been difficult to validation the schema without many examples out in the wild.

can you provide additional configurations in this repo?

Read the linked AWS CDK discussion, then inspect the repository's feature-flag schema and any existing configuration examples. Add representative configurations that validate against the schema; done means the repository contains additional valid examples useful for schema validation.
