Subject: [PATCH] [fix] qwant engine: set header Accept-Language to bypass bot
 detection (#5382)

Set HTTP header Accept-Language [1] for the Qwant engine.

Qwant does not seem to work on any SearXNG instance right now, and this is a fix
for this issue.

During testing, it seems like setting the Accept-Language gives more success for
bypassing bot detection (tested with a few ~20 searches).
