[json-ld serialisation] Context.to_dict() is not implemented (anymore?) #2138
Description
The to_dict() method is missing on Context:
Though this seems to have been implemented and merged before: RDFLib/rdflib-jsonld#51 , it is no longer present in the current codebase. However, it is still referenced: https://github.com/RDFLib/rdflib/blob/main/rdflib/plugins/serializers/jsonld.py#L126 , so this leads to an error if you pass an explicit Context instance:
>>> g.serialize(format='json-ld', auto_compact=True,context=c3)
Traceback (most recent call last):

Perhaps the solution is to re-apply the old pull request?
