Fix redundant reset of terminal in prompt example (#17698)
I know that it's just an example, but I was trying to figure out what was going on and it wasn't making sense.... `tput sgr0` resets the terminal state (http://linuxcommand.org/lc3_adv_tput.php) and I can't see any reason to do it twice. Deleting the second occurrence doesn't seem to break the fancy prompt effect.
