[clean] drop unusable engine: server/project on curlie.org is broken

The websites of https://curlie.org are no longer usable, long runtimes and
recurring "Bad Gateway" messages .. the project is no longer maintained and is
therefore no longer useful in SearXNG.

Related: https://github.com/searxng/searxng/issues/1190
Closes: https://github.com/searxng/searxng/issues/3482
