docs(rpn): fix misleading comment in handleStandardAssign

- Rename comment subject from 'standardAssignHandler' to match actual
  function name 'handleStandardAssign'
- Correct stack position description: in 'name value =' format, name
  is pushed first (bottom of stack) and value second (top), not the
  reverse as the comment previously stated
