dockerfile-kasm-ubuntu-jammy-desktop-vpn misses openconnect as VPN

[seraphyn]

Hello,
it would be great if openconnect could be added as another VPN service.
This would also allow a connection with CISCO Anyconnect

The necessary packages would be :

network-manager-openvpn-gnome 
network-manager-pptp 
network-manager-pptp-gnome 
network-manager-vpnc 
network-manager-vpnc-gnome 
network-manager-openconnect 
network-manager-openconnect-gnome

Thank you in advance

Christian
