The RepositoryService looks for the configuration information in the repository source (supplied by name via the constructor) by default under the "/jcr:system" path. However, the repository example has a configRepository.xml file in which the content is stored under the "/dna:system" path. Although it's possible to use the RepositoryService constructor and specify the correct path, the examples should be such that the path used in the examples is that assumed by the RepositoryService.

Therefore, we should change the repository example configuration file to reflect the current default used by the RepositoryService.
