[BUG] Running "iotedgedev solution init --template csharp" does not generate module.json or dockerfiles for the example module

### Description

Running "iotedgedev solution init --template csharp" does not generate module.json or Dockerfiles for the example filtermodule.

### Expected behavior

I expect to see:
- module.json
- Dockerfile
- Dockerfile.amd64.debug

### Actual behavior

None of the above exist in the module folder

### Steps to Reproduce

Run "iotedgedev solution init --template csharp"

### Environment

Default from "iotedgedev "container image
- iotedgedev, version 3.3.7
- Python 2.7.18
- pip 22.3.1 from /usr/local/lib/python3.9/dist-packages/pip (python 3.9)
- Windows
- Linux iotedgedev container

Start by running `iotedgedev solution init --template csharp` in the stated environment and inspect the generated example `filtermodule` folder. Compare its contents with the expected `module.json`, `Dockerfile`, and `Dockerfile.amd64.debug`; done means all three files are generated there.
