Add cardinality to all objects and properties in the Turtle files

[vikhari]

This is required for the Python API Autogeneration feature to work and should occur for the first stable release of the ontology (before v1.0.0).

@plbt5 - I suggest this issue can be closed. That specific API autogeneration feature is no longer a CASE goal, as it was based on an OWL syntax before the SHACL conversion.

Further, cardinality is now appropriately specified in SHACL ProperyShapes. No sh:min implies minimum 0; no sh:maxCount implies maximum unbounded.
