Params with whitespace error

[hagay3]

While setting params with whitespace I get the following error:

[error] java.lang.RuntimeException: 'minikube version' is not a valid environment variable name

Code example:

githubWorkflowAddedJobs := Seq(WorkflowJob(
    id = "integration-kubernetes-v1-22",
    name = "integration-kubernetes-v1-22",
    steps = List(
      WorkflowStep.Checkout,
      WorkflowStep.Use(
        ref = UseRef.Docker(image = "manusa/actions-setup-minikube", tag = "v2.4.3"),
        params = Map(
         "minikube version" -> "v1.23.2",
         "kubernetes version" -> "v1.22.1",
         "github token" -> "${{ secrets.GITHUB_TOKEN }}")),
      WorkflowStep.Sbt(
        List("It/test")
      )
    )
  ))
