zero-gravity: update zerog.Dockerfile for 0g-mainnet and 0g-galileo-testnet

- Simplified Dockerfile to use 0gchain-NG for all current 0G networks
- Removed special handling for aristotle (0gchain-Aristotle) and galileo
- Supports new chain names: 0g-mainnet, 0g-galileo-testnet
- Uses unified release download URL: https://github.com/0gfoundation/0gchain-NG
