refactor: update dependencies and fix resulting errors

Upgraded JSON Schema from version 6 to version 7 Upgraded TypeDoc version to latest Replaced 'jsonschema' with 'json-schema' package to better comply with 'ts-json-schema-generator' Replace JSON Schema validation with AJV in areas where it wasn't used previously Removed commander help output as it causes strange issues
