v3.3.2 - Update for HA 2024.1

[alexdelprete]

• Replaced deprecated constants (STATE_CLASS_MEASUREMENT, STATE_CLASS_TOTAL_INCREASING) with SensorStateClass enums to prevent HA 2024.1 deprecation warnings
• Removed min. required pymodbus version from manifest, since HA already requires it (https://developers.home-assistant.io/docs/creating_integration_manifest/#custom-integration-requirements)
• Bump the custom component version to 3.3.2

Full Changelog: v3.3.1...v3.3.2
