Docs regression: the search is now showing duplicate results from all the various different versions

[Jane Sandberg]

This is a regression caused by bug 2036328.

Previously, the search dropdown only provided results from latest (aka the main branch). This is the desired behavior, since it is more cluttery with all these duplicate results from all versions.

Here is a branch to do this in the new Antora Lunr way: https://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/sandbergja/lp2056480-only-index-main-in-lunr / user/sandbergja/lp2056480-only-index-main-in-lunr

A test plan from the commit message:
* Build the docs using perl docs/generate_docs.pl --base-url=http://example.com
* Open docs/output/index.html in your browser
* Type a search into the search box
* Note that you only get results for latest, rather than getting duplicate results from multiple versions.
* Note that the file docs/output/search-index.js is now 3.3 MB, rather than the 5.53 MB of the current production file.

Thanks to Blake for catching this issue!

Tested and pushed to main, rel_3_12, and rel_3_11. Thanks, Jane!

Note that I amend the commit message to more accurate describe the test procedure; at present generate_docs.pl works only if you run it from the docs/ subdirectory.
