Add translation to note

When we create a product attribute like this : 

```php
 $installer->addAttribute(Mage_Catalog_Model_Product::ENTITY, "associated_title", array(
       // [...]
        'note'                       => 'My Note',
       // [...]
    ));
```

The note is not translated even if the translation exists.
So this change call the translation for the note information.
