Selecting eth0 Interface in Wizard removes IPv6 address

I want to let AdGuard Home use my IPv4 and IPv6 for the device on eth0, but unless I have "All interfaces" selected, choosing eth0 only shows the IPv4 address available for use.

### Steps to reproduce

1. Install AdGuard Home on Raspberry Pi with active IPv4 and IPv6 connection
2. Run Wizard

### Expected behavior
I can use the IPv4 and IPv6 address via Ethernet

### Actual behavior
Only the IPv4 address can be used.

### Your environment

| Description | Value |
| -------------- | ------------ |
| Version of AdGuard Home server:| v0.94
| How did you setup DNS configuration:| IoT
| If it's a router or IoT, please write device model:| Raspberry Pi 3 Model B +
