[FEATURE] - Route local domain names using system DNS

[Farzat07]

Is your feature request related to a problem? Please describe.
Local domain names do not work (e.g. https://example.internal) as they are tunneled.

Describe the solution you'd like
Such domain names such be resolved by the system DNS (e.g. provided by DHCP) instead of being routed in the tunnel.

Describe alternatives you've considered
Not specifying a DNS in the tunnel, but then I wouldn't be able to block ads using Adguard DNS on my other apps.
