Changes proposed in this Pull Request:

This PR fixes an issue where the address-i18n.js was not firing on initial page loads due to it only being tied to the country on change event causing priority and other local info to be missing.

To remedy this I simply trigger an onchange event on page load to ensure it fires and apply the correct locale info.

Closes #21642

How to test the changes in this Pull Request:

1. Add the following code to your theme's functions.php file

add_filter("woocommerce_checkout_fields", "custom_override_checkout_fields", 1 );
function custom_override_checkout_fields($fields) {
	$fields['billing']['billing_email']['priority'] = 1;
	return $fields;
}

2. Add something to cart and load the checkout page.
3. Ensure the email field is displayed right at the top.
