[System/Storage] API spec bug for schema item kind enum
The API spec enumerates the schema item kind but the code allows a few more types, see implementation in storage-core/src/main/java/org/opengroup/osdu/storage/service/SchemaServiceImpl.java.
Also note that the example in POST /schemas refers to core:dl:geopoint, which is not listed in the enumeration and likely rejected because the code expects core:dl:geopoint:1.0.0, see link above.
