Add more github notification

[lijiarui]

Now

When we push the issue notification, we only have :

1. issue title
2. issue link
3. issue body
4. issue related avatar

But when I use this in WeChat Work, maybe we need more info.

Expect

We need more:

1. issue related developer's name
2. Action: such as add tag, change assignees, close the issue, reopen the issue, comment the issue and so on.

Refer to likai, it make look like this:

I can improve this issue, if it's be needed.

issue close action is important, maybe this is the great beginning of enhancement.
