Is your feature request related to a problem? Please describe.

I'd like to propose a new option at the bottom of the documentation for an object with backlinks to all the places that link to that object.

I think this would make understanding libraries and navigating documentation significantly more powerful.

I'd go so far as to say this would be a "killer feature ™️".

Describe the solution you'd like

I'm sure you can design the look better than me, but I'd propose just a list of bullet points linking to both other code options that link to that object and sections of the documentation which link to it.

I assume since we're talking about square bracket links, this shouldn't be too hard? 🤞

Describe alternatives you've considered

We could do some kind of regex for this, but it would be pretty ugly.

Additional context

In https://ai.pydantic.dev/ I make very heavy use of mkdocstrings links.
