Use correct format for setting environment variables when debugging with cpptools

The RA VSCode extension uses an incorrect format for the environment variables in the `launch.json` when debugging with the C/C++ Extension. This extension uses a different format than CodeLLDB or NativeDebug, which means that the environment variables are not actually set for the debuggee.

What it currently looks like:
```json
"env": {
  "NAME": "VALUE"
}
```

What the C/C++ extension expects:
```json
"environment": [
  { "name": "NAME", "value": "VALUE" }
]
```
