 * npm does not allow you to publish a package with the same version multiple times.
 * Thus, to publish prerelease versions tagged to the branch they're built from,
 * we need to generate unique version numbers that are also higher than versions already published.
 * To achieve this, we append `build<build_number>` to the version number.
 * The actual release version can eventually be published without the suffix.
