Weight in Order Emails

A few years ago I was able to get the weight sent in new order email notifications using the code in this thread.

With my recent upgrade to PHP 8.3, that code seems to be outdated. Is there a new way I can include the order weight in my order notifications?

I appreciate any help you can provide. My current child theme functions.php needs to have this code:

<?php 

add_action( 'wp_enqueue_scripts', 'salient_child_enqueue_styles', 100);

function salient_child_enqueue_styles() {
		
		$nectar_theme_version = nectar_get_theme_version();
		wp_enqueue_style( 'salient-child-style', get_stylesheet_directory_uri() . '/style.css', '', $nectar_theme_version );
		
    if ( is_rtl() ) {
   		wp_enqueue_style(  'salient-rtl',  get_template_directory_uri(). '/rtl.css', array(), '1', 'screen' );
		}
}
