Improve the output of RailsInspect::Cli

[andrewn617]

Motivation / Background

This Pull Request has been created because I want to improve the output of RailsInspector::Cli. The first time I ran into an error from rails inspector, I was confused what it wanted me to do and had to read through the code to understand that I was missing adding my new configuration to cofiguring.md.

Detail

This Pull Request adds and additional line to the output of rails inspector to give the developer more direction, and also prompt them to use the --autocorrect flag.
