magento2: AlertProcessor - Argument #2 ($storeId) must be of type int, string given

Preconditions and environment

• Magento version 2.4.4
• PHP8.1

Steps to reproduce

• Enable product alert stock in BO (Configuration > Catalog >Product Alerts > Allow Alert When Product Comes Back in Stock > Yes, Allow Alert When Product Price Changes - Yes)
• Reindex and cache flush
• Front end - Login as customer - Select a Product without stock - Register to a product stock alert (Notify me when the price drops, Notify me when this product is in stock)
• Add stock to that product from admin
• Launch consumers

Expected result

Alert stock email being sent

Actual result

Emails not triggered for Product Alerts

[2022-06-10T07:31:56.520650+00:00] .CRITICAL: Magento\ProductAlert\Model\Mailing\ErrorEmailSender::execute(): Argument #2 ($storeId) must be of type int, string given, called in /var/www/html/vendor/magento/module-product-alert/Model/Mailing/AlertProcessor.php on line 130 [] []

Additional information

I guess (not tested) that change could solve the issue

Magento\Store\Model\Store

ACTUAL CODE
   /**
     * Get store identifier
     *
     * @return  int
     */
    public function getId()
    {
        return $this->_getData(self::STORE_ID);
    }


PROPOSED FIX

   /**
     * Get store identifier
     *
     * @return  int
     */
    public function getId(): int
    {
        return (int) $this->_getData(self::STORE_ID);
    }

(of course, StoreInterface interface should be modified accordingly.)
