SWORDv2 Python client not compatible with Python 3.12, crashes disseminator.py

[rhigman]

If attempting to run disseminator.py under Python 3.12, the following error is raised:

Traceback (most recent call last):
  File "/home/rh/code/thoth-dissemination/./disseminator.py", line 19, in <module>

    import imp
ModuleNotFoundError: No module named 'imp'

This is because the imp module (used by the SWORDv2 client, which is currently used by the CUL workflow) is no longer supported under Python 3.12.

This error is hit even if the CUL platform is selected, because all of the modules are imported regardless.

The error is not hit if running with Docker, presumably because the Dockerfile is currently configured to use Python 3.10.

thoth-dissemination/Dockerfile

Line 1 in edac5eb

FROM python:3.10

If we wanted to upgrade the Python version in the Dockerfile in future, we would need to work around this. The SWORDv2 client is not under active development, so its use of the unsupported module is unlikely to be fixed. (One option would be to switch to using a more active fork of the client, or create/manage our own.)
