Fix Breadcrumb NavXT breadcrumb rendering

[piit79]

This fixes Breadcrumb NavXT breadcrumb rendering which was removed by in ee748ab1469559c56dd26444089e0cf8646e7e36 (by mistake I assume).

I tested the change (in prod :wink:) on my WordPress/WooCommerce installation.

Summary

This change re-adds the code that calls the bcn_display() Breadcrumb NavXT function to display the breadcrumbs.

Will affect visual aspect of the product

YES (I guess? It adds breadcrumbs that have been missing)
