Add sudo to one command, as it need administrative rights

[PoorPocketsMcNewHold]

As described in the libusb documentation : https://libusb.sourceforge.io/api-1.0/group__libusb__misc.html#gab2323aa0f04bc22038e7e1740b2f29ef

LIBUSB_ERROR_ACCESS	Access denied (insufficient permissions)

While we could give the user access to USB devices, It's far more straightforward to just flash the pad with administrative rights.

I could also reword the text before the command to indicate to execute it with administrative rights, but that's more of a Windows user way of handling it.
