This reverts merge request !21551

Signed-off-by: Tao Wang <twang2218@gmail.com>

This fixes the breadcrumb titles not having links. This was a regression
in the updated breadcrumbs introduced in 10.0.

This introduces the link for all pages rather than selectively doing it.
This will cover issues, merge requests, pipelines, jobs etc.

This fixes an issue where the content has a limited width but the
breadcrumbs remained full width. Instead of creating a new variable
specifically for the breadcrumbs, it just re-uses @content_class
