Update Web/JavaScript/Reference/Global_Objects/Promise/resolve, zh-CN (#2967)

 <div class="blockIndicator warning">
 <p>警告：不要在解析为自身的thenable 上调用<code>Promise.resolve</code>。这将导致无限递归，因为它试图展平无限嵌套的promise。一个例子是将它与Angular中的异步管道一起使用。在<a href="https://angular.io/guide/template-syntax#avoid-side-effects">此处</a>了解更多信息。</p>

+Promise.resolve(thenable)  //这会造成一个死循环
