Update ps_emailalerts.php in $template_vars

[Anton1P]

The problem
I wanted to remake the table in my twig file of the new_order, except that the only variables you created in $template_vars weren't enough, so I suggest you add some variables for more flexibility in customizing the mail template.

The solution
ADD somes variables like =
'{total_paid_tax_excl}' => $contextLocale->formatPrice($order->total_paid_tax_excl, $currency->iso_code), '{total_products_tax_excl}' => $contextLocale->formatPrice($order->getTotalProductsWithoutTaxes(), $currency->iso_code),
