[BUG] Unable to search CLI docs when on docs for an older release of Core

**Describe the bug**
When searching cli docs but on a previous version of uds-core the search results bug out resulting in the search screen flashing with various results, ultimately ending up with no results found.

**To Reproduce**
Steps to reproduce the behavior:
1. Go to a previous version of the core docs like 1.9
2. Click on search and then cli
3. Enter a search term like bundle or next mode
4. See error

**Expected behavior**
Ideally a successful search. Alternatively but less ideal is a message describing to the user that they need to be on the latest version of core docs to search of CLI

**Screenshots**

**Additional context**
Add any other context about the problem here.

Start by reproducing the search flow from a previous Core docs release such as 1.9: open Search, choose CLI, and search for “bundle” or “next mode.” Done means the search returns stable results, or clearly tells users that CLI search requires the latest Core docs.
