Typecho 使用 CommentToDingtalk (评论推送至钉钉)插件遇到的问题

> CommentToDingtalk 项目地址：https://github.com/MoLeft/CommentToDingtalk

# 运行报以下错误

```
Using $this when not in object context
Error: Using $this when not in object context in //nowtime.cc/usr/plugins/CommentToDingtalk/Plugin.php:123
Stack trace:
#0 /nowtime.cc/usr/plugins/CommentToDingtalk/Plugin.php(87): CommentToDingtalk_Plugin::getWebhook('https://oapi.di...', 'SECca000000000...')
#1 /nowtime.cc/var/Typecho/Plugin.php(489): CommentToDingtalk_Plugin::send(Object(Widget_Feedback), NULL)
#2 /nowtime.cc/var/Widget/Feedback.php(146): Typecho_Plugin->__call('Widget_Feedback...', Array)
#3 /nowtime.cc/var/Widget/Feedback.php(336): Widget_Feedback->comment()
#4 /nowtime.cc/var/Typecho/Router.php(138): Widget_Feedback->action()
#5 /nowtime.cc/index.php(30): Typecho_Router::dispatch()
#6 {main}
```

# 原因
在静态方法中调用非静态方法，导致其报错

# 解决方法
将 **静态方法** 中调用 **非静态方法** `$this->` 改成 `(new self())->` 即可

以下是修改后的 `Plugin.php`，你可以直接复制以下代码进行替换：
```
<?php
if (!defined('__TYPECHO_ROOT_DIR__')) {
    exit;
}
