Fix Zenodo upload script

[uellue]

Since recently the script cannot update an existing draft anymore, instead it triggers a "404". We should figure out what is going on and fix the script.

As a work-around one can drop any drafts on Zenodo before minting a new RC or release.

Full error message:

Traceback (most recent call last):
  File "/home/runner/work/LiberTEM/LiberTEM/scripts/zenodo_upload", line 399, in main
    r = update_deposition(deposition_id=deposition_id, data=make_data())
  File "/home/runner/work/LiberTEM/LiberTEM/scripts/zenodo_upload", line 150, in update_deposition
    raise ZenodoException(prettystring(r))
ZenodoException: Status code: 404 
{'message': 'Not found.', 'status': 404}

Possible next debugging steps: the deposition_id used in the update_deposition call comes from get_latest_draft of get_geposition(deposition_id=parent). More concretely, it comes from the latest_draft link.

In the case of the successful update (newly created deposition), latest_draft is something like https://zenodo.org/api/deposit/depositions/11204954 - it would be good to find out how this looks like in the case of updating an existing draft.

Also a note:

def get_latest_draft(r):
    data = r.json()
    url = data['links']['latest_draft']
    parts = url.split('/')
    # The last bit of the URL is the ID
    return parts[-1]

This can be error-prone, maybe instead we should directly fetch the url and access the id of the returned object? Then we don't rely on the exact URL layout (imagine they add a URL parameter, for example, for whatever reason...)
