Add verbal annunciation when charging is complete

🚧 THIS IS A TICKET MIGRATED FROM UPVOTY. The original ticket and comments will be available for a limited time over at:

———————————————————————————
ABRP provides a live estimate for charging progress while stopped at a charger when live data is connected. At some stops I like to take a nap for 20-50 minutes while I wait for charging, but currently I need to estimate when charging will be done and set up a separate alarm to wake me.

It would be convenient if ABRP could have a voice announcement (same as navigation directions) when charging is finished so I can know when to get back on the road without having to look at the display.
