Knative Serving部署后返回Apache默认页面问题求助

• 按Knative官方步骤部署Knative Service，通过YAML文件安装Knative Serving
• 运行环境：WSL2 + minikube + Docker Desktop
• 执行以下命令访问服务：

echo "Accessing URL $(kn service describe hello -o url)"
curl "$(kn service describe hello -o url)"

预期输出为Hello World!，但实际返回Apache 2默认页面的HTML，浏览器访问结果一致。
