update expected exception type when creating devices

[oleksandr-pavlyk]

#826 has modified the type of exception raised when dpctl.SyclDevice could not be created from ValueError to dpctl.SyclDeviceCreationError.

Python examples were not updated. Hence the output of the script shows errors on the manual page about device selection.

This PR updates two affected Python example files, device_selection.py and filter_selection.py.
