Maintenance: Add Ruff as the linter

[leandrodamascena]

Why is this needed?

Ruff is an extremely fast Python linter and code transformation tool, written in Rust.

Ruff can be used to replace Flake8 (plus dozens of plugins), isort, pydocstyle, yesqa, eradicate, pyupgrade, and autoflake, all while executing tens or hundreds of times faster than any individual tool.

• This request meets Powertools for AWS Lambda (Python) Tenets
• Should this be considered in other Powertools for AWS Lambda languages? i.e. Java, TypeScript, and .NET

YES! Make sure to take note of the speed improvement in CI too (this should decrease our installation step + linting, and `make pr` both locally and in CI)
