Adding pre-commit hooks for black and flake8

[rodrigobr-msft]

This pull request introduces pre-commit hooks and updates the development setup to streamline code quality checks and environment preparation. The main changes are the addition of pre-commit configuration, updating development dependencies, and enhancing the PowerShell setup script.

Pre-commit and development tooling:

• Added a .pre-commit-config.yaml file to configure black for code formatting and flake8 for linting, ensuring code quality standards are enforced before commits.
• Updated dev_dependencies.txt to include the pre-commit package, making it available for local development environments.

Development environment setup:

• Enhanced dev_setup.ps1 to automate virtual environment creation, install editable local libraries, install development dependencies, and set up pre-commit hooks for all contributors.

I like Chris' approach of adding documentation better over having a script.
