Add a crumbspath to html encoding

A crumbs path allows users to easily 'browse the api'

Maybe we can only provide a collection switcher and don't "waste" space with breadcrumb for navigating from search to items. A simple back button can be maybe good enough. We have similar requests in GN4 to easily switch from one portal to another.

the point is in case people arrive in a record page from search engine, they can navigate back to the main catalogue page easily

a crumbspath helps people to understand the structure of the api
