Warnings on Depricated constants

[FvanEgmond]

Home Assistant 2024 versions are giving warnings on deprecated constants (see list below). I know this is not a breaking change -and it will only stop working in 2025.1- but for the completeness and correctness, this issue is created, so it can be tracked and addressed somewhere this year. :-) Thanks in advance for fixing!

• STATE_CLASS_MEASUREMENT -> Use SensorStateClass.MEASUREMENT instead
• STATE_CLASS_TOTAL -> Use SensorStateClass.TOTAL instead
• STATE_CLASS_TOTAL_INCREASING -> Use SensorStateClass.TOTAL_INCREASING instead
• DEVICE_CLASS_VOLTAGE -> Use SensorDeviceClass.VOLTAGE instead
• DEVICE_CLASS_CURRENT -> Use SensorDeviceClass.CURRENT instead
• TEMP_CELSIUS -> Use UnitOfTemperature.CELSIUS instead
• DEVICE_CLASS_TEMPERATURE -> Use SensorDeviceClass.TEMPERATURE instead
• FREQUENCY_HERTZ -> Use UnitOfFrequency.HERTZ instead
