Update README.md

[heissanjay]

This Pull request forces the changes in the order of comments in the API response schema section in project's README.md file. Previously, the order of the comments in the API response schema was mismatched, I reordered it so it can match the order of the response schema.

Before changes

{
  // The HTTP status code from the API response
  data: {},

  // The HTTP status message from the API response
  status: 200,

  // The response that was provided by the API
  statusMessage: 'OK',
}

After changes

{
  // The response that was provided by the API
  data: {},

  // The HTTP status code from the API response
  status: 200,

  // The HTTP status message from the API response
  statusMessage: 'OK',
}
