project.config: Reword the description of Code-Review -1

Complaints have been made that patches stall in review, where it's
unclear who is responsible for the next action. It's also been commented
that scoring a patch as Code-Review -1 feels excessive in some
circumstances.

Try to reduce the tension between the two problems by rewording the
description of a Code-Review -1 score and motivate people to use it to
drive the necessary change to a patch.
