Dependency doesn't resolve in sbt

[TobiasRoland]

In the readme, we've got:

"io.scalajs.npm" %%% "express" % "0.5.0"

But this dependency will not resolve. Falling back to "io.scalajs.npm" %%% "express" % "0.4.2" in my build.sbt works - 0.5 will produce error akin to the following when compiling:

Reproducable example

build.sbt:

name := "hello-world"
version := "0.1"
scalaVersion := "2.12.10"
scalaJSModuleKind := org.scalajs.core.tools.linker.backend.ModuleKind.CommonJSModule
scalaJSUseMainModuleInitializer := false
enablePlugins(ScalaJSPlugin)

libraryDependencies += "io.scalajs.npm" %%% "express" % "0.5"

plugins.sbt:

addSbtPlugin("org.scala-js" % "sbt-scalajs" % "0.6.31")

If you've got pointers on how I could work around this to use 0.5, that would be great 👍 - otherwise I'll stick with the 0.4.x for now
