Autobuilder error is caused by an unrelated file; fix is in PR-3288

[cbullinger]

Note to reviewer: open to suggestions on where the new Model Unstructured Data sections might live (unsurprisingly, it's different from SDK to SDK 😉 )

Nice work, @cbullinger! Thanks for getting this all together. Overall, it looks great! A couple things to look at:

High-level things:

• For Node.js, React Native, and Swift, I think it would make sense to move the content to the "Define and Object Model" page. We could have a bit of info + link on the Model Data landing pages, but I think we talked about how those aren't often used.
• I think you need to finish filling out the release notes section of the PR description

My in-line comments are mostly pretty minor.
