Update bluetooth.py

Add alias Y7S , alias of older pinetime.

I am able to successfully connect to my pinetime after adding the Y7S alias

I am able to connect to the pinetime, but am getting an error when trying to flash firmware, 1.0.0 from siglo instructions on pinetime wiki.
Error : dbus.connection :Exception in handler or D-Bus signal:

Ready for merge.
I followed what you did in this commit , and added Y7S to the list of aliases. My pinephone can now find my pinetime.

I think not being able to flash is a different issue.

Sorry and thanks. - Greg
