Removes the Docker service definition from the build stage in the
GitLab CI configuration. This change is made to simplify the build
process and reduce overhead, as the Docker service is no longer
required for the current build tasks.
This change eliminates unnecessary Docker variable definitions from the
.gitlab-ci.yml file, simplifying the CI configuration and reducing
complexity in the build process. The removed variables were not in use
and did not contribute to the current build steps, streamlining the
configuration for better maintainability.
