Add info to automatically add network(s) via Teloscan

[donnyquixotic]

Description Currently shows the steps to manually add the network. It'd be useful to add the steps to automatically add the network(s) via Teloscan navigation.

Possible Solution Add something like this to the Testnet Tutorial and launch-dapp-on-tEVM manual add instructions: "You can visit teloscan.io and click 'Connect' to automatically add the network to MetaMask."
