fix inheritance situation with `SPARQLStore`, `SPARQLUpdateStore`, `SPARQLConnector` and `rdflib.store.Store`.

[aucampia]

SPARQLStore inherits from SPARQLConnector and rdflib.store.Store, however, these two classes have the same methods with different signatures:

rdflib/rdflib/plugins/stores/sparqlstore.py

Line 39 in 0856ac8

class SPARQLStore(SPARQLConnector, Store):

Methods in rdflib.store.Store:

rdflib/rdflib/store.py

Line 334 in 0856ac8

def query(self, query, initNs, initBindings, queryGraph, **kwargs): # noqa: N803

rdflib/rdflib/store.py

Line 350 in 0856ac8

def update(self, update, initNs, initBindings, queryGraph, **kwargs): # noqa: N803

Methods in SPARQLConnector:

rdflib/rdflib/plugins/stores/sparqlconnector.py

Line 81 in 0856ac8

def query(self, query, default_graph: str = None, named_graph: str = None):

rdflib/rdflib/plugins/stores/sparqlconnector.py

Lines 144 to 149 in 0856ac8

	def update(
	self,
	query,
	default_graph: Optional[str] = None,
	named_graph: Optional[str] = None,
	):

This situation should be resolved to avoid LSP violations.
