py-rdflib: updated to 7.0.0

RELEASE 7.0.0

This is a major release with relatively slight breaking changes, new
features and bug fixes.

The most notable breaking change relates to how RDFLib handles the
publicID parameter of the Graph.parse and Dataset.parse methods.
Most users should not be affected by this change.

Instructions on adapting existing code to the breaking changes can be
found in the upgrade guide from Version 6 to Version 7 which should be
available here.

It is likely that the next couple of RDFLib releases will all be major
versions, mostly because there are some more shortcomings of RDFLib's
public interface that should be addressed.
