Title: dev-environment: correct JSON in prefs.json github example

When using the example dev-environment.md's example prefs.json (github section), I get this error:

```
sugar-build]$ ./osbuild shell

raise ValueError("No JSON object could be decoded")
ValueError: No JSON object could be decoded
```

This commit / pull-request fixes that issue by removing the spurious comma from the example JSON.
