Fix AdaptAddStockDataToCollectionPlugin

Nobody has claimed this yet.

Currently we have a plugin \Magento\InventoryCatalog\Plugin\CatalogInventory\Model\ResourceModel\Stock\Status\AdaptAddStockDataToCollectionPlugin

which pluginizes
```


```

Magento\CatalogInventory\Model\ResourceModel\Stock\Status - which is not marked as `@api`

Method which we pluginize
```
/**
* @param \Magento\Catalog\Model\ResourceModel\Product\Collection $collection
* @param bool $isFilterInStock
* @return \Magento\Catalog\Model\ResourceModel\Product\Collection $collection
*/
public function addStockDataToCollection($collection, $isFilterInStock)
```

accpets product collection - \Magento\Catalog\Model\ResourceModel\Product\Collection

but in our implementation we anyway make MySQL join on `catalog_product_entity`
```
$collection->getSelect()->joinInner(
['product' => $resource->getTable('catalog_product_entity')],
sprintf('product.entity_id = %s.entity_id', Collection::MAIN_TABLE_ALIAS),
[]
);
```

so we build such query:

```
SELECT
`e`.*, `stock_status_index`.`is_salable`
FROM
`catalog_product_entity` AS `e`
INNER JOIN
`catalog_product_entity` AS `product` ON product.entity_id = e.entity_id
INNER JOIN
`inventory_stock_1` AS `stock_status_index`
ON product.sku = stock_status_index.sku
WHERE
(stock_status_index.is_salable = 1)
```

which looks very awkward

Start with Magento\InventoryCatalog\Plugin\CatalogInventory\Model\ResourceModel\Stock\Status\AdaptAddStockDataToCollectionPlugin and its Magento\CatalogInventory\Model\ResourceModel\Stock\Status plugin declaration. Inspect how addStockDataToCollection builds the product collection and compare it with the shown SQL query. Done means the stock join no longer creates the redundant catalog_product_entity join while preserving stock filtering.
