Version filtering based on folders

[dandimeo]

Description

The documentation site https://docs.arangodb.com has a folder per version version handling. (all versions are on main branch)
We currently have 3 versions: 3.10, 3.11, 3.12.

We set up Algolia DocSearch V3 and added the following facets:

searchParameters: {
      facetFilters: [`version:${version}`],
}

Version value comes from
var version = localStorage.getItem("docs-version");

However, when the version is switched through version selector and start a new search, the search results still address the previously selected version.

Steps to reproduce

1. Go to https://docs.arangodb.com (will automatically redirect to 3.11 version, which is the stable version)
2. Search something, the behaviour is correct showing 3.11 results
3. Change version via the version selector (e.g. change to 3.12 version)
4. Search something again, it will still show 3.11 results

Expected behavior

Expected behavior is to dynamically change DocSearch facetFilter value for version attribute when site's version is changed.

Environment

• DocSearch version: 3.0.0
