Update the draft content about Debian packaging with something more user
friendly and complete.
I removed the version of the release.json included in the doc and
instead just include the release.json file directly.
I added comments about the configuration parameters directly in the
release.json file, using the convention already being used there.
(If we updated the json python package being used to json5, the
release.json file could include comments using // convention and things
would look a bit cleaner.)
