Load checkout scripts when they are not previously loaded on the checkout page

PR #9984

1. Switch to the develop branch. or plugin version without this change.

2. Ensure you have at least two shipping methods enabled.

3. Add the following filter to your code (e.g., inside functions.php). Note that checking out to the develop branch might overwrite this change, so ensure the filter is re-added if needed. Adjust the shipping method name in the example (local_pickup) to match one you have configured. This filter removes WooCommerce Payments as a gateway for the specified shipping method:

   add_filter(
       'woocommerce_available_payment_gateways',
       function ( $available_gateways ) {
           $chosen_shipping = WC()->session->get( 'chosen_shipping_methods' )[0] ?? '';
           if ( isset( $available_gateways['woocommerce_payments'] ) && 0 === strpos( $chosen_shipping, 'local_pickup' ) ) {
               unset( $available_gateways['woocommerce_payments'] );
           }
           return $available_gateways;
       }
   );

4. Test behavior on the develop branch:

   • Ensure the filter from Step 3 is in place, as switching to the develop branch might overwrite it.
   • Go to the checkout page.
   • Select the shipping method configured in the filter (e.g., local_pickup). Confirm that WooCommerce Payments is not available as a payment option.
   • Switch to a different shipping method. Confirm that WooCommerce Payments is displayed, and payment fields are rendered.
   • Switch back to the shipping method that disables WooCommerce Payments and refresh the page.
   • After the page refresh, switch to another shipping method that supports WooCommerce Payments. Confirm that the checkout blocks or payment fields (e.g., credit card fields) are not rendered.

5. Switch to this branch and repeat the test:

   • Perform the same steps as above.
   • Confirm that this time the payment fields or credit card fields are correctly rendered for the supported shipping methods.
