feat: Upgrade to Jackson 3 (#556)

* Upgrade to Jackson 3

* Change imports for `com.fasterxml.jackson.databind` and `com.fasterxml.jackson.core` to `tools.jackson.databind` and `tools.jackson.core`
* Upgrade `com.networknt:json-schema-validator` to 3.0.0 (Jackson 3 support)
* Adjust Jackson 2 iterators to Jackson 3 collections
* Use non-deprecated `isString` / `asString` / `stringValue` instead of `isTextual` / `asText` / `textValue`
* Use `StringNode` instead of `TextNode`
* Use `JsonMapper#shared` instead of underlying Schema Config `ObjectMapper` in `SubtypeResolutionSimpleIntegrationTest` since schema validation requires numbers, but underlying Object Mapper uses strings for numbers

* Upgrade Java baseline to Java 17 since Jackson 3 is using Java 17
