Add web3 namespace to reth-entrypoint

[Inbell1s]

The web3 namespace was not enabled by default in the http.api and ws.api options within the reth-entrypoint script. This caused compatibility issues with external services, such as Chainlink nodes, which rely on web3_clientVersion for health checks.

This commit adds web3 to the exposed namespaces, ensuring compatibility with standard EVM JSON-RPC expectations.
