Deprecate extra state attributes in Habitica task sensors

[tr4nt0r]

Proposed change

The task sensors in the Habitica integration have extra state attributes containing the complete raw json data of the corresponding task types. The to-do and dailies sensors have already been deprecated as they were migrated to the todo platform. The remaining sensors habits and rewards were not migrated as it is not possible to represent them appropriately. These sensors will remain and display the amount of habits and rewards the users have in their Habitica accounts, only the state attributes will be removed.

when it is detected that these sensors are used in an automation or script a repair issue is raised informing about the deprecation. As the amount of habits and rewards is a number that doesn't tend to change often once set up, it is very unlikely that the state is used for automations. It can be assumed quite safely that the sensors are used in automations for their attributes. Another use for the attributes could be in templates, but i think that cannot be detected in HA.
