We can configure all our Python tooling in a single pyproject.toml file. Note that using pyproject.toml to configure flake8 requires the addition of the flake8-pyproject Python library.
…mmit hook This will ensure that, even when run as a pre-commit hook, flake8 reads its configuration from the pyproject.toml file.

This file was doing nothing due to its contents.
The flake8-docstrings dependency is pinned, so this one should be too.

Pull Request Overview
This PR consolidates Python tool configurations into pyproject.toml, migrating from separate configuration files (.flake8, .isort.cfg, .bandit.yml) to a centralized TOML-based approach. This modernizes the project's configuration management by leveraging the standard pyproject.toml file.
Key Changes:
- Migrated flake8 configuration to
pyproject.tomlusing theflake8-pyprojectplugin - Consolidated isort configuration into
pyproject.toml - Removed bandit custom configuration file and simplified to use defaults
- Updated GitHub labeler to track
pyproject.tomlinstead of removed config files

flake8 itself isn't installed here, so this dependency shouldn't be either. This jibes with the fact that we don't install flake8-docstrings (another dependency of the flake8 pre-commit hook) into the virtual environment either.
