🌱 Integrate global-ci workflow (#41)

## Global CI Integration for Component Builds

This PR integrates a GitHub Action workflow to build and upload the
component images, preparing them for the global CI system.

By integrating the global CI, we aim to streamline and standardize our
CI process across all components, ensuring a more efficient and unified
CI/CD pipeline.
