The engine was added in commit a4b07460 but now it shows new issues [1].
In the 90'th of the last century, dogpile had its own WEB index, but nowadays it
is a meta-search engine [2]
Powered by technology, Dogpile returns all the best results from leading
search engines including Google and Yahoo!
Using dogpile as an engine in SearXNG needs more investigation, a XPath solution
like we have is not enough. It is questionable whether it still makes sense to
investigate more into a meta-search engine with a ReCAPTCHA in front.
With this patch the dogpile engine is removed
