Overview

Similar to #5124, also comes from #5042 (comment), the use of nps makes the script running in this repository much more exotic and as such makes threshold higher for tools like knip as well as to human contributors who are not used to nps.

With 52 180 weekly downloads nps is not an established practice within the community. To make contributions easier we should replace it with ordinary npm scripts instead.
