Subject: [PATCH] [fix] presearch engine: blocked by captcha on every request

Presearch responds with a Cloudflare captcha on each request when using HTTP2.
Using HTTP1.1, everything seems to work fine.

- other engines with the same issue: pixabay, uxwing
- closes https://github.com/searxng/searxng/issues/5438
