Support for JSON5

[bennycode]

I love this extension! But I noticed that jsonAbc.sortObj removes comments from JSON5 files. Would it be possible to keep these during sorting?

Input:

{
  // XYZ
  "xyz": "xyz",
  // ABC
  "abc": "abc"
}

Current Output:

{
  "abc": "abc",
  "xyz": "xyz"
}

Expected Output:

{
  // ABC
  "abc": "abc",
  // XYZ
  "xyz": "xyz"
}
