How to enable gcmode=archive for client Reth

[thanhnguyennguyen]

To enable archive mode for Reth, we need to modify the docker-compose.yml file to add the --prune=false flag, which enables archive mode in Reth. I'll edit the docker-compose.yml file:

services:
  execution:
    build:
      context: .
      dockerfile: ${CLIENT:-geth}/Dockerfile
    ports:
      - "8545:8545" # RPC
      - "8546:8546" # websocket
      - "7301:6060" # metrics
      - "30303:30303" # P2P TCP
      - "30303:30303/udp" # P2P UDP
    command: ["bash", "./execution-entrypoint"]
    volumes:
      - ${HOST_DATA_DIR}:/data
    environment:
      - NODE_TYPE=${NODE_TYPE:-vanilla}
      - PRUNE_MODE=false  # Enable archive mode
    env_file:
      - ${NETWORK_ENV:-.env.mainnet} # Use .env.mainnet by default, override with .env.sepolia for testnet
// ... existing code ...

Now I need to modify the reth-entrypoint script to use this environment variable:

// ... existing code ...
exec $BINARY node \
  -vvv \
