"No module named ...._python_runtime" error happened when lambda running

Got the below run time error when lambda function running in AWS: "_[ERROR] Runtime.ImportModuleError: Unable to import module 'aws_document_extraction_platform_api_python_handlers.get_metrics': No module named 'aws_document_extraction_platform_api_python_runtime' Traceback (most recent call last):_"

And looks like the issue caused by the folder of "aws_document_extraction_platform_api_python_runtime" not included in the folder of "packages/lib/dist/lambda"

After inserting the below codes into .projerc.ts, the issue fixed in my testing:

// this line code to resolve the ...python_runtime dependencies for step functions
```
pythonLibrary.packageTask.exec(
`cp -r ${path.join('../api/generated/runtime/python/aws_document_extraction_platform_api_python_runtime')} dist/lambda/`
);
```

// this line code to resolve the ...python_runtime dependencies for api handlers
```
api.handlers.python!.packageTask.exec(
`cp -r ${path.join('../../generated/runtime/python/aws_document_extraction_platform_api_python_runtime')} dist/lambda/`
);
```

Start in .projerc.ts and inspect how packages/lib/dist/lambda is assembled for the AWS Lambda handlers and step functions. Reproduce the reported import failure, verify that aws_document_extraction_platform_api_python_runtime is included in the deployment folder, and confirm the get_metrics handler loads successfully.
