Kousuke Saruta 94e040d059 [SQL][DOCS] Remove wrong example from DataFrame.scala
In DataFrame.scala, there are examples like as follows.

```
 * // The following are equivalent:
 * peopleDf.filter($"age" > 15)
 * peopleDf.where($"age" > 15)
 * peopleDf($"age" > 15)
```

But, I think the last example doesn't work.
