Use wireguard-turn-android as recommended app

Replace the recommended Android client in README.md and README.en.md: swap vk-turn-proxy-android for wireguard-turn-android and update the link and brief description (it's a modified WireGuard client with built-in TURN). Remove the previous explicit WireGuard config/exception steps from the recommended method while leaving the Termux alternative unchanged.
