Breadcrumbs text and default links fail contrast ratio

https://v5.getbootstrap.com/docs/5.0/components/breadcrumb/

The active text/separator for breadcrumbs uses #6c757d on #e9ecef with a contrast ratio of 4:1. The default links in breadcrumbs use #0d6efd on #e9ecef with a contrast ratio of 3.8:1.

bumping the text/separator from $gray-600 to $gray-700 (#495057) shoots up the contrat to 6.9:1. For the links, however, there's very little wiggle room ... not sure how/if that can be tackled - #0d6efd has a ratio of 4.5:1 only against pure white, so even lightening the breadcrumbs background a bit won't help
