debugging with `"type": "aws-sam"` launch configuration fails

## Problem
When trying to run a local lambda function with configuration of type `aws-sam`. Getting
```text
connect ECONNREFUSED 127.0.0.1:5858
```

When using the sam cmd vscode is invoking and running it manually in powershell i'm getting:

```text
(general-env) PS C:\xxxxxx\PycharmProjects\unigen_pipeline> sam.cmd `

Reproduce the `aws-sam` launch configuration on Windows using the reported `.aws-sam/build/template.yaml`, event and env-vars JSON files, and the generated SAM command. Start with the `py_debug_wrapper.py` traceback and the missing `debugpy` import; done means local invocation starts the debugger and no longer fails with ECONNREFUSED.
