Wireguard Documentation - Access Internal Devices needs updating

[paul-da]

Hi, I ran in to the issue in this discourse where Unbound stops working after configuring Wireguard:

https://discourse.pi-hole.net/t/wireguard-and-unbound/66715/19

Using the updated NFT commands there sorts it. The commands and the example in the doc need updating:

Kind regards,
Paul.
