 * The plugin generates lots of these on php v8.4:
 *     ```wp-block-code
       PHP Deprecated:  Woo_Stripe_Pay_Addons\Core\Stripe_Customer::map_customer_data(): Implicitly marking parameter $wc_customer as nullable is deprecated, the explicit nullable type must be used instead in /wp-content/plugins/payment-addons-for-woocommerce/includes/core/stripe-customer.php on line 370
       ```
