Mark Neo4j notebooks passed in demo notebook testing, not soft-fail (#1067)
Mark Neo4j notebooks passed in demo notebook testing, not soft-fail (#1067)

We're now testing the Neo4j notebooks on CI (#1046), as a separate step to the
main demo notebook testing one. The notebooks cannot be run in main step because
they have dependencies (the GraphSAGE notebooks need to run the Cora ingestion
notebook first, and all of them need to have py2neo installed), and so its
correct to filter them out of that step, however filtering them out as "soft
failures" is misleading: these notebooks aren't temporarily broken, they're
permanently being tested elsewhere.

We can thus make our build summary convey exactly how many notebooks we're not
testing (9 out of 36), by marking the parallel jobs that "run" (i.e. skip) the
neo4j notebooks as passed, since they've successfully done what they're meant to
do.
