[BUG] <title>webhook send alter message error

[Ykubernetes]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

During alarm recovery, sending a message containing a threshold expression causes the content field to contain special characters
for example：
{
"alarmId": 76456,
"target": "${target}",
"thresholdId": 33455,
"priority": 0,
"content": "alert **** , status("up")",
"status": 0,
"times": 1,
"triggerTime": "2022-02-25T13:32:13",
"tags": {
"app": "windows",
"monitorId": "180427708350720",
"metrics": "availability",
"code": "UN_CONNECTABLE",
"thresholdId": "112",
"monitorName": "WINDOWS_192.168.124.12"
}
}

"content" is not a valid JSON format and has not been escaped

Expected Behavior

hertzbeat 用于Apache Jexl处理表情，你可以详细了解它的使用方法，或者参考

!equals(status,"UP")
There are double quotes. When sending notification recovery, adding this expression to the content field will cause a json format error.

Hi, this should be a problem caused by inserting special content into the json template. We will fix it by escaping it later.

你好，这应该是在 json 模板中插入特殊内容导致的问题，我们稍后会通过转义来修复。

好的
