Similar to what is outputted when a user installs a targetted deprecated package version.
npm i deprecatedPackage@1.2.3 // `npm WARN deprecated deprecatedPackage@1.2.3 ...`
we should warn the user by default when the latest package version is itself, deprecated.
E.g if the latest version was indeed
1.2.3 and that version was deprecated then the following should happen:
npm i deprecatedPackage // `npm WARN deprecated deprecatedPackage@latest ...`
