[hibernate-dev] ORM Quicks Starts and Tutorials

A quick heads up that I just completed migrating the ORM quick start guides from DocBook to Asciidoctor (HHH-9916). Part of this was to upgrade the versions of asciidoctorj and the asciidoctor-gradle-plugin used in the build. Let me know if y'all see anything awry. As far as styling, we currently just use the Asciidoctor default styling without any branding etc. When I find some time I would like to look at styling and branding these a bit better. For the most part I like the style, I would just like to see our logos, header imsages, etc integrated.
