Correct demonstration URL in route helper example (#10844)

The example for the route helper currently shows a relative URL:

```
// /user/1/profile?photos=yes
```

However, the route helper returns an absolute URL by default, since the third parameter is not set to false. The corrected example should be:

```
// http://example.com/user/1/profile?photos=yes
```

This change ensures the documentation matches the actual behavior of the route helper.
