🐳 Chore: TLS certificate verification error for L1 RPC connections

[koofree]

Problem

• failed to verify certificate: x509: certificate signed by unknown authority #1

Solution

Added ca-certificates package to both Docker containers (node and geth) to provide the necessary root certificates for TLS verification.

Changes

• Updated node/Dockerfile to install ca-certificates
• Updated geth/Dockerfile to install ca-certificates

This ensures the containers can properly verify SSL/TLS certificates when connecting to external HTTPS endpoints.

I am not sure this is the best answer for #1. But this will make it work.

Thanks for contributing.
For better readability, could you please format this line using multi-line style? (+ node/Dockerfile)
