Describe the feature

Aurora Serverless V2 now allows scaling to zero (https://aws.amazon.com/blogs/database/introducing-scaling-to-0-capacity-with-amazon-aurora-serverless-v2/), but there is validation in CDK that prevents any values less than 0.5.

This validation needs to be removed.

Use Case

You should be able to scale the Aurora Serverless V2 cluster to 0.

Proposed Solution

Modfity /packages/aws-cdk-lib/aws-rds/lib/cluster.ts and remove the greater that 0.5 validation.
