ConvertFrom-Json returns array with extra null element, if comments are outside the root element. #21203

Description

@mubed

Prerequisites

Steps to reproduce

Having a json file containing this:

// Comment on top level
{
    "key": "value"
}

should become a PSObject or Hashtable, when imported using Get-Content and then piped through ConvertFrom-Json, but the result is an array with a null as first element and the PSObject/Hashtable as the second element!

Expected behavior

Comment lines have to be ignored, not be included as null elements.

Actual behavior

Comments on top level are interpreted as null elements like a "{}".
