Pulumi azure-native provider: Azure WebApp: The parameter LinuxFxVersion has an invalid value

Question

I created a new Pulumi Typescript program using the Pulumi CLI with pulumi new azure-typescript and created the following index.ts (based on the new azure-native provider):

import * as pulumi from "@pulumi/pulumi";
import * as azure from "@pulumi/azure-native";

const resourceGroup = new azure.resources.ResourceGroup("rg-spring-boot", {location: "West Europe"});

const appServicePlan = new azure.web.AppServicePlan("sp-spring-boot", {
    location: resourceGroup.location,
    resourceGroupName: resourceGroup.name,
    kind: "Linux",
    sku: {
        name: "B1",
        tier: "Basic",
    },
});

// Image https://hub.docker.com/r/jonashackt/spring-boot-vuejs
const imageName = "jonashackt/spring-boot-vuejs:latest";

const appServiceSpringBoot = new azure.web.WebApp("spring-boot-vuejs-azure", {
    location: resourceGroup.location,
    resourceGroupName: resourceGroup.name,
    serverFarmId: appServicePlan.id,
    siteConfig: {
        linuxFxVersion: `DOCKER|${imageName}`,
    },
    httpsOnly: true,
});

Now running a pulumi up -y I get the following error:

As stated in this so answer the problem lies within the Azure AppService configuration in azure.web.AppServicePlan. Although we set the kind: "Linux", it's actually a Windows machine.

The missing parameter is reserved: true, inside our AppService:

const appServicePlan = new azure.web.AppServicePlan("sp-spring-boot", {
    location: resourceGroup.location,
    resourceGroupName: resourceGroup.name,
    kind: "Linux",
    reserved: true,
    sku: {
        name: "B1",
        tier: "Basic",
    },
});

As the documentation states without setting reserved parameter to true we got a Windows machine. This even show up in the Azure Portal, if you use kind: "Linux" without the parameter:
