…tor upgrade

In `com.networknt:json-schema-validator:1.4.0`, these methods have been
renamed:
-  `getUri` -> `getIri`
- `defaultMetaSchemaURI` -> `defaultMetaSchemaIri`
These methods have been marked as deprecated, I've replaced it with
these equivalent methods:
- `addKeywords` -> `keywords`
- `addMetaSchema` -> `metaSchema`
