E-Bike demo is using deprecated mapbox classic style API

Preconditions:

• B2Qt 5.15.2 updated to Toradex Apalis iMX6 target  device
• target device connected to ethernet network

Steps to reproduce:

• Open E-Bike app in startup screen demo and go to navigate view

Expected result:

• Map shows terrain (roads etc.)

Observed result:

• Terrain is not shown

Also tried to set destination to New York. In this case route to destination is drawn and e-bike starts cycling towards it successfully but terrain is still not visible. The bug is there also using Intel NUC target device.
