examples: Remove unneeded meta tag from blog example

```html
    <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
```
This was only needed for IE10 and lower (which are no longer supported) and chromeframe which was a Google plugin for IE8 and lower and was discontinued many years ago. So this meta tag can be safely removed.
