remove unnecessary execution env vars (#4806)

<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->
## Summary by CodeRabbit

- **Refactor**
- Removed environment variable tracking for `NODE_ID`, `JOB_NAME`, and
`JOB_NAMESPACE` in job execution.
- Updated test cases to remove node-specific verifications and focus on
partition-specific outputs.
- Adjusted expected outputs in tests to reflect changes in environment
variable priorities.
