fix args in suave-enabled-chain (devenv) docker-compose

[zeroXbrock]

📝 Summary

Problem: can't hit the execution node (suave-enabled-chain).
request:

# assuming devenv stack is running via docker-compose
curl -X POST --data '{"jsonrpc":"2.0","method":"eth_getBlockByNumber","params":["latest", true],"id":1}' -H "Content-Type: application/json"  http://localhost:8555

response:

curl: (56) Recv failure: Connection reset by peer

Solution: changes to suave-enabled-chain in docker-compose:

• hosts JSON-RPC APIs on 0.0.0.0, needed for the node to listen outside the container
• opens up CORS
• maps the local suave-ex-node directory to access the keystore file
