Updating the website to include how to stream Dandi datasets

Hello! I really appreciate what you guys have done!

I noticed in the download Data and Dandsets part of the [website](https://www.dandiarchive.org/handbook/12_download/), it only includes how to hard download data, not how to stream it. Thanks to the hackathon I know there is a [tutorial](https://github.com/NeurodataWithoutBorders/nwb_hackathons/blob/main/HCK21_2024_Janelia_NDRH/notebooks/read_basics_and_stream.ipynb) made for streaming data instead. Perhaps, incorporate that into the main website as well?

Thanks
