🐛 fix(vpn): displays DNS name in vpn status

[pallabpain]

Description

This PR fixes the rio vpn status command to show the DNS name of nodes instead of the host name registered with headscale. The DNS name is the one that is resolved by MagicDNS and not the host name and thus, it seems more intuitive to show the DNS name. The host name can be inferred from this name as well.

Testing

→ pipenv run python -m riocli vpn status
ℹ️ VPN is enabled in the project (lgs-hmr-001)
