Jackson 3 `JsonNode#required(java.lang.String)` throws `JsonNodeException` different from JavaDoc

I'm currently migrating a project from Jackson 2 to 3.
I noticed that tools.jackson.databind.JsonNode#required(java.lang.String) now throws a JsonNodeException if the property is missing while the JavaDoc claims that an IllegalArgumentException is thrown. So one of them is probably wrong. 😉

Intent is for JsonNodeException to be thrown, not IAE -- IAE was for 2.x when we could not throw checked (in 2.x) JacksonExceptions.

So Javadocs to be fixed, not exception.
(Which PR does, yay!)

Backported fix in 3.0.3 as well.
