Issue 541: Add Event

In an OWL-only sense, the ontology portion of this patch could have been
accomplished by adding one triple to `action:Action`.

For the sake of symmetry and explicitness, `core:Event` also picked up
the `owl:disjointWith` statement.  To satisfy OWL syntactic
requirements, a stub reference to `action:Action` is added, as was done
for `types:Dictionary` for Issue 541 (discussed in PR 542).

To enforce disjointedness with SHACL, a new independent shape is added,
`action:Action-disjointWith-Event-shape`.

A follow-on patch will regenerate Make-managed files.

EDIT 2023-11-22: An initial version of this patch included an inlined
anonymous `sh:NodeShape`.  I now believe the scenario that shape
mitigates (multi-import of a shapes graph leading to SHACL-scoped syntax
errors) is unlikely, and I also saw that the noted rationale around
`sh:not` was confused with another predicate (`sh:inversePath`).

This causes `ValidationResult`s to yield sufficient information to find
the whole triple that should have used a sequence.  With the prior
spelling, only the object of the triple would have been directly
identified; the predicate could be manually deduced from the shape name;
and the subject was completely absent from the validation result.

The noted comment on PR 572 illustrates the difference in results when
testing CASE-Corpora.  The issue is replicated as new PASS and XFAIL
test members.

A follow-on patch will regenerate Make-managed files.
