[FEAT]: Add searXNG to the list of live web searching and browsing

[HakaishinShwet]

What would you like to see?

Main reason for wanting this is to have free and pretty great and selfhostable alternative to serper,google,bing search apis which are free upto some limits and then we have to pay, but if we are able to integrate searxng in this great project then many people can use search thing for free without much issues. https://github.com/ItzCrazyKns/Perplexica/ perplexica have implemented this same thing which give people option to use searxng as search option instead of paying for api usage. With docker it becomes much more easy to selfhost and then connect with using url. You can see there docker compose and setup and see for yourself how they are using it and then add searxng in this project docker compose and give option to users to select searxng option if they want to So this was my experience of one great project perplexica from which i liked that particular thing so thought to share here so that u can understand first what i meant and then implement it. This will be great addition to this awesome project. Hope to see it get implemented soon.If you wanna ask something more regarding this then do let me know i will try my best to give proper info on that if possible. Thankyou very much for all the hardwork devs :-)

I would love that too; since I already host my searx and allow result JSON like possible to use via the API
