fix(rds): serverlessV2MaxCapacity can be set to 0.5, which is invalid

[mazyu36]

Issue # (if applicable)

N/A

Reason for this change

In CFn docs, MaximumCapacity value must be higher than 0.5 ACUs.

The maximum capacity must be higher than 0.5 ACUs.

This means MaximumCapacity cannot be set to 0.5 ACUs.
However, in the CDK, serverlessV2MaxCapacity can be set to 0.5, which is invalid.

When I attempted to deploy with serverlessV2MaxCapacity set to 0.5, I encountered the following error:

CREATE_FAILED | AWS::RDS::DBCluster | Integ-Cluster (IntegCluster4261F36F) Resource handler returned message: "Serverless v2 maximum capacity 0.5 isn't valid. The maximum capacity must be at least 1.0.

In the Management Console, Maximum Capacity cannot be set to 0.5.

Description of changes

Fix a validation.

Description of how you validated changes
