refactor(ci): streamline build evaluation logic in pipeline (#505)

- Simplifies the logic for build evaluation by using environment variables instead of shell scripting.
- Reduces redundancy in the evaluation steps for build, build_push, build_configuration, and release.
- Improves clarity and maintainability of the CI configuration.
