What happened to this? It doesn't seem to be working for me, with aws-s3-deployment and cdk 1.112 🤔

This PR is about showing Docker output during bundling. aws-s3-deployment doesn't use bundling by default but if you use BucketDeployment with an asset that uses bundling the output should be shown. If not, please open an new issue.
