文档中middleware.go默认模版和源代码不一致

What is the name + path of the page that needs changed? The relative path
and page title where you found a problem.
这是cloudwego中middleware.go的模版：

      {{define "M"}}
      func {{.MiddleWare}}Mw() []app.HandlerFunc {
      	// your code...
      	return nil
      }
      {{range $_, $router := $.Children}}{{template "M" $router}}{{end}}
      {{- end}}

      {{template "M" .Router}}  

这是Hertz源码中的默认模版:

{{define "M"}}
{{- if ne .Children.Len 0}}
func {{.GroupMiddleware}}Mw() []app.HandlerFunc {
	// your code...
	return nil
}
{{end}}
{{- if ne .Handler ""}}
func {{.HandlerMiddleware}}Mw() []app.HandlerFunc {
	// your code...
	return nil
}
{{end}}
{{range $_, $router := $.Children}}{{template "M" $router}}{{end}}
{{- end}}

{{template "M" .Router}}

router.go的模版也有类似的问题

@tqqq 模板后面路由都有一些更新，文档中没有及时更新，你可以提个 pr 帮忙改下吗
