Update to OrientDB 3.1.16 to support Apple Silicon

I experience local test failures both in latest master and in this PR, so not sure this introduces regressions.

Have same problem (see error below), but not a problem if I just upgrade the version at runtime (see also my comment at #709)

Superseded by #765.

@jbaron The tests use a path as the DB name and OrientDB v3.1.x has an issue with the slashes, which v3.0.x didn't. This isn't a problem in 99% of real life scenarios where the DB name will most likely be "cache". While the upgrade to v3.1.x is pretty seamless it does require a change to JBake relating to the retrieval of tags.

Thanks @kwin for looking into this and raising the PR in the first place.
