DLP: created and last updated metrics are confusing

[bendichter]

Currently, for published dandisets, the DLP shows "Created" and "Last Updated" e.g.:

https://dandiarchive.org/dandiset/000350/0.221219.1506?page=4&sortOption=0&sortDir=-1&showDrafts=true&showEmpty=false&pos=31

Created December 19, 2022
Last update December 19, 2022

I was confused by this because I expected these dates to be the time that the dandiset was created and the time that it was last updated, however these dates refer to the dandiset VERSION, not the dandiset itself. I find this counter-intuitive, since for a specific version these dates are always the same (a VERSION of a dandiset is a publication, so it is static, so the last time it is ever modified is when it is created). Because of that fact, I naturally assumed that these metrics were corresponding to the dandiset as a whole. To get that, you would need to go to the "draft" page of a dandiset. That's fine, but it caused me a lot of trouble trying to debug a dashboard that was showing access of a dandiset before I thought it was created. Does anyone else find this confusing?

IMO

The Created <datetime> text should always refer to the creation time of the Dandiset itself

The text to the right of that should then be Last update <datetime> (if on draft version) or otherwise Published <datetime> (if version has been published)
