The index.html in the released package is wrong

Download from: https://github.com/LoeiFy/Mirror/raw/master/release/mirror.zip
Only these codes in index.html:

```
<!doctype html>
<html>
<head>
<meta charset="UTF-8" />
<title> Falco </title>
</head>
<body>
<div id="root"></div>
<script src="./index.0fbaafc4.js"></script>
</body>
</html>
```
The correct code is in index.sample.html
