#37722: wp_remote_retrieve_headers no longer an array in WordPress 4.6

 With the introduction of Requests in PHP 4.6, headers are returned as a
 `Requests_Utility_CaseInsensitiveDictionary` object instead of a native
 PHP array, see `wp-includes/class-wp-http-requests-response.php >
 get_headers`. Although this object implements `ArrayAccess`, it
 technically is no longer an array and this causes a plugin of mine to
 break due to incompatible types, as I assert that an array is given.

 Documentation and docblocks needs to be updated to reflect this change.
