Fix the configurationAttributes of edb Attach to Erlang Node option (#98)

Summary:
The configuration attributes were misconfigured. When using `Attach to Erlang Node` launch.json
complains about missing properties of "node", "cwd", and property  "config" is not allowed.

So, update these attributes in package.json to fix the issues.
