Support for content IDs for more stable linking between products/apps and docs

[bbkingery]

My product has a lot of in-app links, but the docs are also growing fast and need frequent reorganization. It would be awesome if Mintlify offered a way to generate content IDs that could be used in the product and then mapped to a page URL in a configuration file. This would reduce the risk to potentially have product links that go to redirects of redirects. I'm also dealing with in-app links that go to specific page headings, which can't (as I understand it) redirect at all. This enhancement would be really valuable in putting management of in-app links within the hands of Docs teams without requesting updates from UX or engineering.
