Script puts ```--add-interface``` in PostDown rather than ```--remove-interface```

On line 262 the script puts bash PostDown = firewall-cmd --zone=public --add-interface=${SERVER_WG_NIC} && firewall-cmd --remove-port ${SERVER_PORT}/udp && firewall-cmd --remove-rich-rule='rule family=ipv4 source address=${FIREWALLD_IPV4_ADDRESS}/24 masquerade' && firewall-cmd --remove-rich-rule='rule family=ipv6 source address=${FIREWALLD_IPV6_ADDRESS}/24 masquerade'" >>"/etc/wireguard/${SERVER_WG_NIC}.conf"

Surely this should say bash PostDown = firewall-cmd --zone=public --remove-interface=${SERVER_WG_NIC} && firewall-cmd --remove-port ${SERVER_PORT}/udp && firewall-cmd --remove-rich-rule='rule family=ipv4 source address=${FIREWALLD_IPV4_ADDRESS}/24 masquerade' && firewall-cmd --remove-rich-rule='rule family=ipv6 source address=${FIREWALLD_IPV6_ADDRESS}/24 masquerade'" >>"/etc/wireguard/${SERVER_WG_NIC}.conf" in the postdown section instead
