Feature request: Add Wireguard support

Add Wireguard installation template

I'll consider this one. It'll be this or openVPN. It'll auto configure. I do have openVPN working with PiHole and optionally allowing forwarding to LAN, but I only managed to get that part running on x86 architecture. ARM kept failing. If Wireguard just "works" then I'll probably use it instead. Wireguard also looks a lot more promising.

Hi,
linuxserver/wireguard is a Good Container!
But I have problems to configure the port mapping in my Fritzbox router.
Can you add a documentation for that?

@SaJaToGu Not sure about the Fritzbox specifically, but can add some documentation on port forwarding in general. Each router has a different UI, it would be almost impossible (and create a HUUGE amount of work) to add a how-to-port-forward for every router. We would also need each router, so that we can take screenshots and test out the instructions etc.
