Summary of Changes

Hello @ohmayr, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request modernizes the project's Python code quality tooling by migrating from a combination of black and isort to the single, high-performance ruff tool. This change simplifies the development workflow by consolidating formatting and import sorting into one command, aiming to improve efficiency and maintain consistent code style.

Highlights

• Tool Replacement: Replaced black and isort with ruff for Python code formatting and import sorting across the project's noxfile.py configurations.
• Nox Session Updates: Modified the lint and format nox sessions to utilize ruff's capabilities for checking imports, formatting, and applying fixes.
• Deprecation of blacken session: The blacken nox session has been deprecated and now internally calls ruff format, with a warning message guiding users to the format session.
• Exclusion Logic: Updated the exclusion logic for linting paths to align with ruff's glob-based exclusion patterns, replacing black's regex-based exclusions.

Code Review

This pull request effectively replaces isort and black with ruff for code formatting and import sorting across various noxfile.py configurations. The changes are logical, and I appreciate the effort to maintain backward compatibility by deprecating the blacken session with a clear warning. My review focuses on improving maintainability by ensuring the newly introduced RUFF_VERSION constant is used consistently across all session.install calls.

is this right? It seems like there's no space between the -c and the update_service_yaml
