fix: cli parsing - handle correctly false value for validator (#146)

* Rename command-line argument from `--validate-integrity-sha512` to `--validate-integrity`
* Add validator only if commandValue is not falsy
* Added tests to make sure validator does not run when flag is missing, or flag is set to "false"
* Added another cli test for the integrity validator
* Refactor: Add validator only if commandValue is not falsy
