Add IPv6 Control Decky plugin

[spmzt]

Add IPv6 Decky to Plugin Store

A plugin to control IPv6 on the Steam Deck from the Quick Access Menu.
SteamOS disables IPv6 by default and reverts the setting on every update.

Choose an IPv6 mode without leaving Game Mode:

• System default: the plugin changes nothing.
• Enabled: IPv6 is kept enabled.
• Disabled: IPv6 is kept disabled.
• IPv6 only: IPv6 is kept enabled and IPv4 is turned off on Wi-Fi and Ethernet.

Can verify that the IPv6 Control plugin works as intended on SteamOS Stable and fixes a quirk with SteamOS (Steam Deck) where with dual-stack networks it only utilizes one (IPv4 or IPv6), disabling the other.

#1127 I'm introducing IPv6 connectivity support that allows IPv6 support as well, adding compatibility for this plugin.
