This update for mygnuhealth fixes the following issues:

- version 2.2.0
  * Support for Kivy 2.3.0
  * Localization. MyGNUHealth now has support for different languages.
    English, Spanish and Chinese are available to use, and French,
    German, Italian are ready to be translated. There will be a
    translation component for MyGNUHealth at Codeberg's Weblate
    instance. 
  * Bluetooth functionality: Starting with MyGH series 2.2 we provide
    bluetooth integration for open compatible devices and health
    trackers. We include the link with the Pinetime Smartwatch
    (experimental) and the possibility to link to any open hardware
    device (glucometer, scales, blood pressure monitors,  .. ). We need
    to get a list of available medical devices that respect our privacy
    and freedom, so let us know of any! 
  * Charts now allow to select date ranges with calendar widgets The
    Book of Life have a revised format for the pages. The charts have
    been improved in the format and include x axis labels.
