npm version to add alpha postfix
While -alpha and -beta are common prerelease tags, they are not defined by SemVer. -alpha.1, -alpha.2, -beta.1, etc, are also fairly common. The spec defines the prerelease tag as a series of dot separated alphanumeric or numeric character fields. The SemVer spec uses alpha and beta in some examples, but they are not defined by the spec.
