new release ready to go

[mr-c]

Dear @stain , I've prepared a new release of cwlprov-py that support RDFLib 7.x. Can you run python -m build and upload the result to PyPI?

Better yet, can you transfer https://pypi.org/project/cwlprov/ to https://pypi.org/org/CWL/ and then we can share the maintenance?
