OOBE: Update Fingerprint Enrollment aria_label

Currently, in the fingerprint enrollment flow we instruct the users to
place their fingers either on the power button or on the fingerprint
sensor without specifying the exact location of the fingerprint sensor

In this CL, the aria_labels are updated to provide the users with the
exact location of the fingerprint sensor on their devices.
