`Mangrove.connect` fails on local node when given url is `localhost`.

Describe the bug
Mangrove.connect fails on local node when given url is localhost:8545. It succeeds however when given url is 127.0.01:8545

To Reproduce
Steps to reproduce the behavior:

const provider = new ethers.providers.JsonRpcProvider(
  "http://localhost:8545"
);
let wallet = new ethers.Wallet(<PRIVATE_KEY>, provider);
let mgv = await Mangrove.connect({ signer: wallet });

That sequence fails with:

Uncaught:
Error: missing response (requestBody="{\"method\":\"net_version\",\"id\":46,\"jsonrpc\":\"2.0\"}", requestMethod="POST", serverError={"errno":-61,"code":"ECONNREFUSED","syscall":"connect","address":"::1","port":8545}, url="http://localhost:8545", code=SERVER_ERROR, version=web/5.6.1)
[..]
requestBody: '{"method":"net_version","id":46,"jsonrpc":"2.0"}',
requestMethod: 'POST',
serverError: [Error],
url: 'http://localhost:8545'
}

This is likely due to localhost being interpreted as "address":"::1" because of IPv6 configuration.

This is still relevant. I recreated the error.

And it has been fixed.
