Improve cf push examples
Previously, the examples in this repository for pushing applications read as `cf push -b https://github.com/cloudfoundry/java- buildpack.git`. While this would work in cases where there was a manifest for the application, it lead to confusion among users. This change makes the examples more verbose, but much more clear and, we hope, reduce the amount of confusion. see: https://groups.google.com/a/cloudfoundry.org/d/topic/vcap-dev/ROJfb0SJ5PA/discussion [#68430712]
