Old testnet network config

[kirill-serkin]

Hi! I tried to use this repository, but as it turned out, the network configuration for the testnet is outdated. There is still rinkebay which is not used and manually changing the config to goerli does not work. Also, moonbeam should be called moonbase and change the rpc endpoint for it since this one does not work. Also, the website shows the new gateway contract addresses but the configuration is the same as before. Can you fix this?
