Description

We inadvertently removed the @hashicorp/versioned-docs dependency here, but it's still referenced so we actually need it!

PR Checklist 🚀

Items in this checklist may not may not apply to your PR, but please consider each item carefully.

• Add Asana and Preview links above.
• Conduct thorough self-review.
• Add or update tests as appropriate.
• Conduct reasonable cross browser testing for both compatibility and responsive behavior (We have a Sauce Labs account for this, if you don't have access, just ask!).
• Conduct reasonable accessibility review (use the WAS as a guide or an axe browser plugin until we establish more formal checks).
• Identify (in the description above) and document (add Asana tasks on this board) any technical debt that you're aware of, but are not addressing as part of this PR.
