[Nokia][DeviceData] Update the Nokia platform IXR-7250E device data (#16028) (#16381)

Why I did it
Update the platform_reboot of Nokia Platform IXR-7250E-36x400G to displays the correct reboot-cause history when reboot from supervisor card.

Work item tracking
Microsoft ADO (number only):
How I did it
Modify the platform_reboot script to copy the correct reboo-cause.txt file from NDK to the /host/reboot-cause directory at the down cycle when the reboot is issued from Supervisor (for both reboot right after install a new image and normal reboot)
