bundleDependencies property is rewritten incorrectly

[djcsdy]

Input:

{
  "name": "awesome-web-framework",
  "version": "1.0.0",
  "bundleDependencies": [
    "renderized",
    "super-streams"
  ]
}

Output:

{
  "name": "awesome-web-framework",
  "version": "1.0.0",
  "bundleDependencies": {
    "0": "renderized",
    "1": "super-streams"
  }
}

Expected output: same as input.

The bundleDependencies field is defined as an array, see: https://docs.npmjs.com/cli/v8/configuring-npm/package-json#bundledependencies

It can also be spelled bundledDependencies (with an extra d), in which case the same problem occurs.
