Changes

Please provide a summary of what's being changed

This PR downgrades AWS CDK-related dependencies to 2.145.0 - last known working version for us - so that we can continue the release process for our packages.

I have verified that both aws-cdk and aws-cdk-lib are no longer present in our dependency tree by running npm ls <package-name>, below the results:

npm ls aws-cdk-lib                                                                
aws-lambda-powertools-typescript@0.0.1 /Users/aamorosi/Codes/aws-lambda-powertools-typescript
├─┬ @aws-lambda-powertools/testing-utils@2.3.0 -> ./packages/testing
│ └── aws-cdk-lib@2.145.0
├─┬ layers@2.3.0 -> ./layers
│ └── aws-cdk-lib@2.145.0
└─┬ powertools-sample-app@2.3.0 -> ./examples/app
  └── aws-cdk-lib@2.145.0
