Upload fails with invalid dist_id

In scientific-python/upload-nightly-action#77 @larsoner saw

Error:  ("Invalid dist_id ObjectId('6603800020b28178c3fabc66') does not exist", [404](https://github.com/h5py/h5py/actions/runs/8445531348/job/23133109268#step:5:405))

The dist_id seems to come from the payload of the upload command

and given the 404 it seems this is a problem on the Anaconda Cloud side of things. Can a better error message be added for the user?
