docs: added make target 'autogenerated-json' to Makefile

- this command exports the configs into json files from the bareos-binaries
  and then rebuilds the config rst files
- whereas 'autogenerate' just autogenerates the config rst files from the
  already present json files; this helps if someone just wants to build
  the documentation but does not have the binaries to export the config
