Update docker images on new commit

[thiagolunardi]

This pull request adds a step to the GitHub Actions workflow to log in to Docker Hub before building Docker images. This ensures that the workflow can authenticate with Docker Hub, which is necessary for pulling private images or pushing images to the registry.

Workflow improvements:

• Added a Docker Login step using the docker/login-action@v3 action, with credentials sourced from repository secrets, before the image build process in .github/workflows/build.yml.
