This pull request includes several changes aimed at simplifying the configuration process, updating documentation, and improving code consistency. The most important changes include updates to the configuration format, refactoring import statements, and adding new linting tools configuration.

Configuration and Documentation Updates:

• .github/workflows/python-package.yml: Updated the build and install paths to use ${INSTALL_PATH}, and modified the config.yaml creation to reflect the new dependency structure.

Linting Tools Configuration:

• pyproject.toml: Added configuration for linting tools such as Ruff and Codespell, and specified rules and exceptions for code quality checks.

Code Consistency Improvements:

• tests/tiramisu/test_schedule.py, tests/tiramisu/test_tiramisu_server.py, tests/tiramisu/tiramisu_actions/test_distribution.py, tests/tiramisu/tiramisu_actions/test_expansion.py, tests/tiramisu/tiramisu_actions/test_matrix.py: Made minor adjustments to method calls and assertions to improve code consistency.
