Rename 'Sleep mode' switch (#714)

* Rename 'Sleep mode' switch

Renamed from `Sleep Modus` to `Sleep mode`.

Breaking change: This will rename the entity_id of that switch and this can affect existing automations created by users and also will require changes in the blueprint if #698 is merged.
Note: Variable names in HMI/TFT not renamed.
