~test_path_length.test blocked by cwida/duckdb-pgq#17~

snb_bi_20_1.test Needs more work. Changed the sf to 0.1 but that has changed the output. Need to verify with Neo4j what the output should be before continuing

test_graphblas_graph.test should have the path returning function changed after the merge of cwida/duckdb-pgq#18
