Ensure a package is exactly the latest version as in npm.org.
Useful when you have a shared package depended by many other projects, and you desperately want all to be using the latest version of that package.
Usage:
$ npx assert-latest chalk
Please upgrade chalk from version: ^4.1.0 to 4.1.1
$ npx assert-latest lodash
lodash is already the latest version: 4.17.21
