@jsklan made this PR: #7638 to which my question was "what is referenced-packages"?

This issue to document what referenced-packages is, when to use it, and what subscription plans it's available on.

Hey Danny.
I went deeper into the codebase and especially PR (7638).

ApiReferenceNodeConvertor.ts and ApiReferenceNodeConvertorLatest.ts have a reference to referenced-subpackages.

To document referenced-packages:

1. Create new file - fern/pages/docs/api-references/referenced-subpackages.mdx
2. Register and update this new entry in docs.yml

Let me know if I can work on the documentation part.

Hey @dannysheridan,
I made a PR ( #8065 ) adding documentation for referenced-packages.
Unfortunately, it has a few issues causing CI checks to fail.
One warning in docs.yml: WCAG Contrast Warning
Two warnings in the .mdx file: Endpoint Path Conflicts

Fortunately, these are warnings and not the errors!
Do you think I should address these warnings as well?
