non-compatible azd-sample in the playground

[vhvb1989]

The playground/publishers project is non-compatible with AZD b/c it can't produce a manifest entry for:

IResourceBuilder<IComputeEnvironmentResource> environment = builder.Configuration["Deployment:Target"] switch
{
    "k8s" or "kube" => builder.AddKubernetesEnvironment("env"),
    "aca" or "azure" => builder.AddAzureContainerAppEnvironment("env"),
    _ => builder.AddDockerComposeEnvironment("env"),
};

Please skip this resource when publishing --manifest
