Fixes collapsing repo name on current work item section

Description

Reverts plain repo icon

This PR fixes #4387 that keeps an element expanded because it holds focus after a click.

The previous solution f31b51a reverted implementation of one of requirements of #4332, where it required to replace integration icon with a simple repo icon, and another regression has been noticed:

Fixes collapsing of focused

Therefore I reverted it and applied the ignorance of the :focus-within property by breadcrumbs in active-work element without affecting breadcrumbs behavior in other places of GitLens. I did it by adding a new optional property that can customize this property: whether the :focus-within should be considered or ignored on collapsing.

Fixes width movement on hover

Also it solves another issue that has been recently reported:

work-item-breadcrumb-hover.mov

I didn't do anything special for that, just cannot reproduce it after my changes.
