Simply manually removing @types from folder before zipping.

How to verify this change

It is not breaking layer capabilities: https://github.com/awslabs/aws-lambda-powertools-typescript/actions/runs/3530267827

You can manually verify the improvment by deploying the layer to your own account (cd layer-publisher && cdk deploy) and check either the cdk.out/assets or download the published layer from AWS Console.
