Update firmware page small clarification suggestion

[haikusw]

The Updating Firmware page in the wiki: https://github.com/BlueSCSI/BlueSCSI-v2/wiki/Updating-Firmware has instructions for "USB Method" and the fourth bullet says "You can verify it has the new version by looking at the log.txt on the SD card." however it didn't say to insert an SD card before that in the instructions and I hadn't done so.

New to BlueSCSI and so wasn't sure about updating the wiki directly or not so making an issue until I know more how you wish to work her.

Hey @haikusw! Just go ahead and edit the wiki any way you see best - thanks for seeing something and putting in the effort to update it - enjoy your BlueSCSI and let us know if there's anything else we can help you with.
