CI: gets targets from docker buildx file
I cannot test this on my fork as the ci requires a secret from this repo

Thanks for the PR. I tried to fix the CI failure

Error when evaluating 'strategy' for job 'build'. .github/workflows/CI.yml (Line: 43, Col: 17): Error from function 'fromJson': empty input, .github/workflows/CI.yml (Line: 43, Col: 17): Unexpected value ''

But it does not correct. The error is still present.

Pull Request Overview

This PR modernizes the CI workflow by dynamically extracting build targets from the docker-bake.hcl file instead of maintaining a hardcoded list in the GitHub Actions workflow. This approach ensures the CI automatically stays in sync with the Docker build configuration.

Key changes:

• Added a new job to dynamically extract targets from the Docker bake file
• Replaced hardcoded target matrix with dynamically generated targets from the bake file
• Introduced dependency between jobs to pass extracted targets to the build job
