[Scripting] Appending a current file with `writeToFile`

[NghiaTranUIT]

Description

Currently, the writeToFile() in the Scripting will override the existed file.

function onResponse(context, url, request, response) {

  // Write to single file
  writeToFile(response.body, "~/Desktop/body.json");
  
  // Write the Body to file with flow ID
  writeToFile(response.body, "~/Desktop/sample-" + context.flow.id);
  
  // Done
  return response;
}

=> Some users would like to append content to the current file, not override them.

Acceptance Criteria

• Able to Override or Append to the current file
