Pass $websiteId as a parameter instead of $storeId

The method getProductPriceData expects $websiteId as a parameter, but $storeId was given. It should be $websiteId since prices are website specific. Also see \Magento\Elasticsearch\Elasticsearch5\Model\Adapter\DataMapper\ProductDataMapper where a similar method exists and $websiteId is used.
