As a data curator, I'd like to be able to use the GUI to deaccession multiple datasets

While checking deposits in the Harvard Dataverse Repository, I occasionally have to deaccession multiple datasets that don't contain data (they often contain only research articles) while I learn more from the depositor about their intentions and data availability.

Deaccessioning reduces the chance that deposits will appear when people are looking for data and gives the depositors a chance to create new dataset versions with data. (If the depositor can't add data or doesn't reply, I later delete the published deposit.)

When I need to deaccession multiple datasets, I have to do so by visiting each dataset page. It would be a lot faster to be able to deaccession multiple datasets at once using the GUI. It's already possible using the Dataverse API.

Start by examining the existing GUI flow for deaccessioning one dataset and the already-supported Dataverse API operation. Define how users select multiple datasets and confirm the action; done means multiple datasets can be deaccessioned through the GUI without visiting each dataset page.
