🧹 [Code Health] Remove unused 'sys' import in tag_release.py

[edithatogo]

🎯 What: Removed the unused sys import from scripts/maintenance/tag_release.py.
💡 Why: The sys module was imported but not referenced anywhere in the script, as verified by static analysis. Removing unused imports improves code clarity, prevents potential namespace pollution, and maintains a clean codebase without affecting functionality.
✅ Verification: Verified the removal visually and successfully ran ruff check configured in the project on the file with no errors reported.
✨ Result: A cleaner tag_release.py file with slightly improved code health and readability.
