issue

If there is a configuration parameter, which is an array of elements, and you have multiple default elements, it is not generating valid yaml

input

     "defaults": [ "a", "b", "c"]

actual

defaults: [
   "a"
   "b"
   "c"
]

expected

defaults: 
   - "a"
   - "b"
   - "c"

Proposal

By using YAML.stringify we have the appropriate behavior, with the usage of https://www.npmjs.com/package/yaml (additional dependency). Instead of doing replacements within the JSON string to currently generate the YAML.
