javaagent is not added on version 2.1.0 when forked

[qwe2]

The following code prints [] when running on sbt-kanela-runner 2.1.0:

package foo

import java.lang.management.ManagementFactory

object Foo {

  def main(args: Array[String]): Unit = {
    val bean = ManagementFactory.getRuntimeMXBean()
    println(bean.getInputArguments)
  }
}

build.sbt:

lazy val root = (project in file("."))
  .settings(
    name := "runner-issue",
    organization := "com.example",
    version := "1.0-SNAPSHOT",
    crossScalaVersions := Seq("2.13.14"),
    libraryDependencies ++= Seq(
      "io.kamon" %% "kamon-bundle" % "2.7.3",
    ),
    (run / fork) := true,
  )

When run on 2.0.14 instead, it correctly prints:

[-javaagent:<repo path>/io/kamon/kanela-agent/1.0.11/kanela-agent-1.0.11.jar]
