Same reason why we do this for the app version in the "release" file. Why would it be different?

 - What would `RuntimeVersionReader` and `ModuleVersionReader` return for this input?
 - Why would the `JarVersionReader` strip the "-SNAPSHOT" prefix? On Linux, there are no restrictions similar to those of macOS and Windows for version string. "1.2.3-SNAPSHOT" is a valid rpm/deb version.
