Broken SBT export

[yadavan88]

Version(s)
version: 1.4.0

Describe the bug
When exporting the scala-cli project to sbt (and possibly the same for mill), the build configuration for scalaVersion is generating wrongly if the full scala version is not used in the directive

To Reproduce
Sample.scala file

//> using scala 3
@main def main = println("Hello!")

Export using:
scala-cli --power export Sample.scala --sbt

try to run this sbt project using sbt run. It fails due to the build.sbt having wrong scala version:

scalaVersion := "3"

Expected behaviour
It should be scalaVersion := "3.3.4" probably the lts version. It could be having the same issue in mill export as well.
