[Userscript] Simple 404 Community not found straight to local search

If you try to access a community on your local instance and it gives you a 404, this automatically takes you to your local instance’s search instead and puts the community in for you.

Recommended to use with sh.itjust.works/post/33762](local instance redirect script) by @soy

I started using Tampermonkey today, so dunno if this works with GreaseMonkey, but I assume it does.
