[Documentation] Java API --> Client

Minor issue.

Docs currently:

Node node = nodeBuilder().node();

should be:

Node node = NodeBuilder.nodeBuilder().node();

Well. If you do this:

import static org.elasticsearch.node.NodeBuilder.*;

It should work, right?

[dadoonet]

But BTW thanks for raising it. I will use Node node = NodeBuilder.nodeBuilder().node(); instead as we did in other parts of the Java guide.

Actually, we decided previously not on repeat the class name in examples when doing static method imports. See discussion here: #6920 (comment)

So the current documentation looks good to me. Closing but feel free to reopen if you think I'm wrong.
