require('worker_threads') is not an instance of EventEmitter. So
once method would not be in it. The correct way to receive the message
would be to attach a listener to the message event on the
parentPort.

Also, there is no built-in event called workerMessage. This patch
fixes it by referencing message event.

I think in this case the norm is to link worker_threads.parentPort and 'message' separately, to something like

received via [`worker_threads.parentPort`][]'s [`'message'`][`port.on('message')`] event.

`require('worker_threads')` is not an instance of `EventEmitter`. So
`on` method would not be in it. The correct way to receive the message
would be to attach a listener to the `message` event on the
`parentPort`.
