Optimise Python tooling infrastructure

[kieran-ryan]

🤔 What's changed?

• ruff linter and formatter over black, isort and flake8
• Renovate automated dependency updates for pre-commit

⚡️ What's your motivation?

• Improve maintainability
  • Enforces import formatting - which although had a configuration, it was not validated in the pipeline and imports were thus not formatted
  • Automatically update Python linting dependencies
• Improve developer experience
  • Standardises across gherkin, messages and expressions
• Removed deprecated poetry APIs before they are removed; and the following warning on builds: The "poetry.dev-dependencies" section is deprecated and will be removed in a future version. Use "poetry.group.dev.dependencies" instead.

🏷️ What kind of change is this?

• 🏦 Refactoring/debt/DX (improvement to code design, tooling, etc. without changing behaviour)

♻️ Anything particular you want feedback on?
