Designate action:Action and core:Event disjoint

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`).
