Doc search should not show deprecated results

Describe the bug

The search feature in the book/docs returns misleading results about deprecated versions. If I search 'startup', the first result is Startup commands (jonathandturner), which is very outdated. The URL does indicate that this is old, but that's not part of the search result, and you have to scroll to the top of the page to see the version number (and you'd already have to be a user to know that this is not the newest version).

Thank you.

How to reproduce

Navigate to https://www.nushell.sh/ and search for startup

Expected behavior

I guess the expectation is that the search function would only draw from docs that are current relative to the latest version.

Additional context

No response

Reproduisez la recherche startup sur https://www.nushell.sh/ et examinez comment les résultats incluent des pages obsolètes du livre ou de la documentation. Suivez le point d’entrée de la recherche du site et les métadonnées de version ; la tâche est terminée lorsque la documentation de la version actuelle est renvoyée sans résultats obsolètes trompeurs.
