doc: suggest worker threads in cluster docs
The current documentation is incorrect in that it says "A single
instance of Node.js runs in a single thread," which is not true due
to the addition of worker threads.
This patch removes the incorrect statement and instead suggests that
applications consider using worker threads when process isolation is
not needed.
