Early semver labels are wrongly added

[dpevunov-cp]

I suppose that in some cases 'early-semver-<major/minor/patch>' are wrongly added to the PRs produced by scala-steward
Currently there is a code below to define the severity of change for early-semver. Judging by the definition I would say it should return None if major is not zero which in turn will lead to earlySemVerLabel not having 'early-semver-<major/minor/patch>' for dependency changes with major > 0

I have found that even in your test the lable is wrongly added for the following dependency changes

val update1 = ("ch.qos.logback".g % "logback-classic".a % "1.2.0" %> "1.2.3").single
val update2 = ("com.example".g % "foo".a % "1.0.0" %> "2.0.0").single
val update = Update.Grouped("my-group", None, List(update1, update2))

val earlySemVerLabel = semVerVersions.flatMap { case (curr, next) =>
        SemVer.getChangeEarly(curr, next).map(c => s"early-semver-${c.render}")
      }

@tailrec
  def getChangeEarly(from: SemVer, to: SemVer): Option[Change] = {
    val zero = "0"
    // Codacy doesn't allow using `if`s, so using `match` instead
    (from.major === zero, to.major === zero) match { // work around Codacy's "Consider using case matching instead of else if blocks"
      case (true, true)
          if from.minor =!= zero ||
            to.minor =!= zero ||
            from.patch =!= zero ||
            to.patch =!= zero =>
        getChangeEarly(
          from.copy(major = from.minor, minor = from.patch, patch = zero),
          to.copy(major = to.minor, minor = to.patch, patch = zero)
        )
      case _ =>
        getChangeSpec(from, to)
    }
  }
