Scala JS always uses CrossVersion.for3Use2_13

[JD557]

Describe the bug

Scala JS always uses CrossVersion.for3Use2_13, even for libraries that only work with Scala 3.

To Reproduce

1. Create a Scala.js project
2. Set the Scala version to Scala 3
3. Add a Scala 3 only library
4. Notice that the library is included with CrossVersion.for3Use2_13

Expected behavior

When the selected Scala version is Scala 3, scastie should use Scala 3 libraries.

I think the issue is

scastie/api/src/main/scala/com.olegych.scastie.api/ScalaTarget.scala

Lines 211 to 212 in 0e1f7bf

	def renderSbt(lib: ScalaDependency): String =
	s"${renderSbtCross(lib)} cross CrossVersion.for3Use2_13"

Maybe it should look like

scastie/api/src/main/scala/com.olegych.scastie.api/ScalaTarget.scala

Lines 286 to 291 in 0e1f7bf

	def renderSbt(lib: ScalaDependency): String = {
	if (Some(lib) == runtimeDependency) renderSbtDouble(lib)
	else if (lib.target.binaryScalaVersion.startsWith("2.13"))
	s"${renderSbtDouble(lib)} cross CrossVersion.for3Use2_13"
	else renderSbtDouble(lib)
	}

? Not sure.
