chore(deps): bump yaml and aws-cdk-lib in /examples/servers/cat-facts

Removes [yaml](https://github.com/eemeli/yaml). It's no longer used after updating ancestor dependency [aws-cdk-lib](https://github.com/aws/aws-cdk/tree/HEAD/packages/aws-cdk-lib). These dependencies need to be updated together.


Removes `yaml`

Updates `aws-cdk-lib` from 2.243.0 to 2.245.0
