update upload page to point to the NWB GUIDE for conversion and for upload.
Main changes:
Move conversion to NWB to the top. I found it a bit awkward to have this step in the middle of the upload workflow. If the data is not yet in NWB, the user should probably start there.
Incorporate NWB GUIDE, both for data conversion and for data upload. The GUIDE now provides a user interface for the entire data upload process, and I think this would be a more comfortable route for most DANDI users.
Formatting. I like to start each bullet with a title. The text was moved around a bit to try to improve the logical flow
