**Description**
<!--
Please include a summary of the change and which issue is fixed. Please
also include relevant motivation and context. List any dependencies that
are required for this change.
-->
⚒️ When chaning the UDP Port. Wg-easy stops working. Reason: Wg-easy
always uses 51820 inside the container. WG-PORT is only used for
generating the QR-Codes and Configs. Added TargetPort to fix this issue.
From wg-easy README: 
> The public UDP port of your VPN server. WireGuard will always listen
on 51820 inside the Docker container.
