Fixing waitgroups example.

Instead of printing

Worker 6 starting
Worker 6 starting
Worker 6 starting
Worker 6 starting
Worker 6 starting
Worker 6 done
Worker 6 done
Worker 6 done
Worker 6 done
Worker 6 done

It should print something like

Worker 5 starting
Worker 2 starting
Worker 4 starting
Worker 1 starting
Worker 3 starting
Worker 3 done
Worker 4 done
Worker 5 done
Worker 2 done
Worker 1 done

I just updated my local go version to 1.22.1 and indeed the old code works as expected. Thank you for the link
