fix: use makeFirstResponder

Apple docs explicitly say: "never invoke this method directly" for becomeFirstResponder and resignFirstResponder

This was causing the following crash:
  "ExceptionsManager.js:73 Exception thrown while executing UI block: NSWindow: -_oldFirstResponderBeforeBecoming is not a valid message outside of a responder's implementation of -becomeFirstResponder."
