Syntax coloring for using directives without double quotes in Metals

[lwronski]

Is your feature request related to a problem? Please describe.
When the scala-cli doesn't require double quotes for using directives, Metals color keywords with the same color as values.

//> using dep com.lihaoyi::os-lib:0.9.1
//> using test.dep org.scalameta::munit::0.7.29
//> using toolkit latest

object Hello extends App {
  println("Hello")
}

Describe the solution you'd like

Values are coloured with different color than keywords.

Och, we might need to update it in the VS Code extension if anyone has time.

Fixed it for semantic highlight in scalameta/metals#5301

What do you think?

We still need to fix it in https://github.com/scala/vscode-scala-syntax/blob/78750edc8babd117616290e507697a46cbadc85a/src/typescript/Scala.tmLanguage.ts#L1020, since it won't work with semantic highlighting turned off

@jkciesluk Thank you for working on this issue, it's really cool. It looks nice to me. @MaciejG604, do you have any thoughts?
