Clarification Request
It is not possible for me to run an integration test in my current AWS account. Would be someone so kind, do this and update this MR accordingly?

I downloaded the branch to my local, and confirmed the changes are generating the rotation lambdas using python 3.10. I will add a exception to the test since they are in a nested stack within the integ tests stacks, and they are not being recognized, but I did check they end up creating lambdas with python v 3.10 for test packages/@aws-cdk-testing/framework-integ/test/aws-secretsmanager/test/integ.hosted-rotation.ts
