flash_nuke.uf2 not compatible with BlueSCSI Ultra RP2350

[efpob]

The flash_nuke.uf2 linked at https://github.com/BlueSCSI/BlueSCSI-v2/wiki/Updating-Firmware does not work with the BlueSCSI Ultra

I needed to use the one from https://datasheets.raspberrypi.com/soft/flash_nuke.uf2

I've updated the link, thanks! Please feel free to edit the wiki in the future if you find any issues.
