Pypi project description is now empty

See https://pypi.org/project/kiwixstorage/0.10.0/

It was not previously: https://pypi.org/project/kiwixstorage/0.9.0/

Probably deserve a patch release (especially now that CI is in place, it is going to be easy).

Saw this in Publish job:

https://github.com/openzim/python-storagelib/actions/runs/19034751830/job/54356276256

Note it is also probably the first time we are using v1.13 of pypa/gh-action-pypi-publish action, might be related ... or not ^^
