Please release a new version with fix for model download

[mikegerber]

b049e47 fixed the model download, but is not in the release.

With 0.3.0 you can't download the model using ocrd resmgr download ocrd-eynollah-segment default:

I believe this warrants a hot-fix.

This took me a while to understand. @kba Is it possible to improve the error handling in the resource manager a bit, e.g. print out a clear error that path_in_archive from ocrd-tool,json (incl. mentioning field and JSON) does not exist in the archive? That would have helped and I believe this could be problem that will come again.

Workaround is to install the current main branch into a temporary venv and use that to get the model:

# (in a temp venv)
pip install git+https://github.com/qurator-spk/eynollah.git@main
ocrd resmgr download ocrd-eynollah-segment default
