[PATCH pve-docs 1/1] sdn: fabrics: wireguard: update endpoint documentation

[Stefan Hanreich <s.hanreich@proxmox.com>]

The split of the endpoint field into endpoint + port field has been
reverted. Update the documentation to reflect this change as well.
Since this has caused confusion while testing, add explicit examples
on the expected values for internal / external nodes respectively.
