Support response streaming for Node.js image

Hello,

I'm trying to debug a Node.js function that streams a response locally, but it seems the image doesn't support it.

The image I'm using is `public.ecr.aws/lambda/nodejs:20`.

This invocation doesn't work (response is "404 page not found"):
```bash
curl -v -XPOST "http://localhost:9000/2021-11-15/functions/function/response-streaming-invocations" -d '{}'
```

This invocation works:
```bash
curl -v -XPOST "http://localhost:9000/2015-03-31/functions/function/invocations" -d '{}'
```

Full cURL output:

```
