Increment a version code following SemVer Scheme

@param semver [String] the version code to update, e.g. “1.2.3” @param increment_type [String] the version code to update, e.g. “1.2.3” @return [String] the version code updated according to increment_type

@example Default increment (patch)

increment_semver("1.2.3")  #=> "1.2.4"

@example Increment for given type

increment_semver("1.2.3", "major")  #=> "2.0.0"
