[Console] Doc Block: More intuitive usage example in ArrayInput.

Make the ArrayInput doc block example more self-explanatory and less misleading. Show the common use case of having `command`, and replace the confusing `name` argument with something more arbitrary.

The current doc block example for `ArrayInput` seems to imply that the command name goes in as `name`, but this is actually just a random argument, named "name", in this case.
```php
new ArrayInput(['name' => 'foo', '--bar' => 'foobar']);
```

It might be more helpful to provide an example that works with Symfony's `Console` component out of the box, as that is a common use case:
```php
new ArrayInput(['command' => 'foo:bar', 'foo' => 'bar', '--bar' => 'foobar']);
```
