Allow water_heater entity in climate card

Thanks for your project !

water_heater entities are not yet supported in the climate card.
These entities are really similar to climates: https://www.home-assistant.io/integrations/water_heater/

Hi! Can you try to add it in YAML to see if it works like that? If yes I will just have to allow them in the entity list in the editor.

Edit: It seems that they are some differences, maybe not for the v2.3.0, I need to stop adding features in this beta 😅

The card display is working properly. However, the temperature change functionality is currently not responding to user input.
Let me know if you'd like me to provide more technical details.
