variable support for dependency versions

Is your feature request related to a problem? Please describe.

compared to sbt:

val quillVersion = "4.7.3"

libraryDependencies ++= Seq(
  // Syncronous JDBC Modules
  "io.getquill" %% "quill-jdbc" % quillVersion,
  // Or ZIO Modules
  "io.getquill" %% "quill-jdbc-zio" % quillVersion,
  // Or Cassandra
  "io.getquill" %% "quill-cassandra" % quillVersion,
  // Or Cassandra + ZIO
  "io.getquill" %% "quill-cassandra-zio" % quillVersion,
  // Add for Caliban Integration
  "io.getquill" %% "quill-caliban" % quillVersion
)

there's no easy way to pin multiple libraries to same version in scala-cli.

//> using dep io.getquill::quill-jdbc:4.7.3
//> using dep io.getquill::quill-jdbc-zio:4.7.3
//> using dep io.getquill::quill-cassandra:4.7.3
//> using dep io.getquill::quill-cassandra-zio:4.7.3
//> using dep io.getquill::quill-caliban:4.7.3

Describe the solution you'd like

introduce using val (syntax can change) directive to make it easier to pin multiple dependencies to same version.

//> using val quillVersion = "4.7.3"
//> using dep "io.getquill::quill-jdbc:$quillVersion"
//> using dep "io.getquill::quill-jdbc-zio:$quillVersion"
//> using dep "io.getquill::quill-cassandra:$quillVersion"
//> using dep "io.getquill::quill-cassandra-zio:$quillVersion"
//> using dep "io.getquill::quill-caliban:$quillVersion"

Describe alternatives you've considered

not adding it, it's more of an inconvenience.
