Date format incorrect on post items currently Month day, year. Should be day/month/year

Describe the bug
Date format incorrect on post items (entry date and updated) Should be day/month/year as per NHS guidance we have received.

Changing get_the_date and get_the_modified_date in inc/template-tags.php to the following fixed it for me:
$time_string = sprintf(
$time_string,
esc_attr( get_the_date( DATE_W3C ) ),
esc_html( get_the_date('d/m/Y') ),
esc_attr( get_the_modified_date( DATE_W3C ) ),
esc_html( get_the_modified_date('d/m/Y') )
);
