index_format = "elasticlunr_json" is using the default_language for all indexes

[Jieiku]

Bug Report

A new json index_format was added: #1998

The problem is this new json index generation does not seem to support multiple languages, the indexes are identical:

Environment

Zola version: 0.17.2

Expected Behavior

It should generate a different index per language.

Current Behavior

All the indexes are the default language.

Step to reproduce

git clone --branch refactor https://github.com/Jieiku/abridge
cd abridge
zola serve

Fix

I believe I spotted the problem: Jieiku@7af04b2

This does indeed create the separate indexes:
