Python 3.12 and Ceiling Fan Fixes

[JeffSteinbok]

Major Changes

• Python 3.12 Support

This pull request includes several updates to enhance the functionality and compatibility of the Dreo fan integration and its testing framework. The most important changes involve updating the Python version in the CI workflow, expanding fan features, and adding new test cases.

Compatibility and Setup:

• Updated the Python version in the GitHub Actions workflow from 3.11 to 3.12 in .github/workflows/pytest.yaml to ensure compatibility with the latest Python release.

Feature Enhancements:

• Expanded the supported features of the fan to include TURN_ON and TURN_OFF in custom_components/dreo/fan.py.
• Introduced FAN_MODE_STRINGS dictionary to map mode strings to user-friendly names in custom_components/dreo/pydreo/constant.py.
• Updated the parse_preset_modes method to use FAN_MODE_STRINGS for mode identification in custom_components/dreo/pydreo/pydreofan.py.

Testing Framework:

• Added new test cases for the HCF005S fan model in tests/pydreo/test_pydreofan.py to verify fan speed and preset modes, and to ensure commands are sent correctly.

Dependency Management:

• Replaced pytest-homeassistant-custom-component with homeassistant in requirements.test.txt to streamline dependencies.
