[Steppers] Add example for breadcrumbs using Steppers

[bdeloeste]

As per #13176, included an example in docs for using <Steppers /> to implement breadcrumbs.

I'd add a description here along the lines of: "The stepper components can be repurposed to create navigation breadcrumbs."

Trivia - breadcrumbs were one of the first web-server plugin components I ever created (back in 1998), but I didn't know they were called that then, so it was called "clickable path".

[bdeloeste]

Done :)

I did some digging to try to find the origin and also found another alias: "Cookie crumbs" (https://en.wikipedia.org/wiki/Breadcrumb_(navigation)).

I also did some digging, and would you believe, it's still out there!

This was for Roxen, a web server that was so far ahead of its time. You could add plugins ("modules"), and their configuration page would show up in the web server's web GUI. It supported "RXML" which allowed you to embed tags in your html pages, that would then be converted by the respective module to HTML, images, etc. when the page was requested.

Sadly Apache won out at the time, and Roxen went on to become a niche CMS.

@oliviertassinari I saw your screenshot, are there still issues indexing Breadcrumbs for Algolia?

[mbrookes]

@bdeloeste GitHub has been having issues, leading to repeated comments / lost comments, and so on.

I believe the image that @oliviertassinari posted was showing that you are resolving one of the top items that users search for that currently comes up blank. Consider it a big 👍 for this PR!

[oliviertassinari]

I'm wondering about mixing the Stepper use case with the Breadcrumb 🤔. Let me benchmark the alternatives, just to be sure.

[eps1lon]

@oliviertassinari I had the same concerns. As per #8818 (comment) I would rather create the described utility component and document breadcrumbs as a possible use case.

You could argue that breadcrumbs are somewhat steps down a hierarchy but a Stepper is IMO for things that are on the same level whereas breadcrumbs are on different levels. It's really only about semantics but Stepper adds a lot of overhead for a simple breadcrumbs use-case.

[bdeloeste]

Hm, @eps1lon I agree. Stepper also has the idea of "seeing into the future" and knowing there's going to be a "finish".

[mbrookes]

@bdeloeste Thanks for taking the time to create this PR 🙏, but following the subsequent discussion, it seems this isn't the right way forward. Let's close for now.
