Update CI example docs.
Docs for CI examples are updated as follows:
- Fix a dead link from CI example top to `dpl`
- Specify Django for a Python project, not Rails
- Use the latest Python Docker image as [Heroku supports only Python 3.5.1 (and 2.7.11)](https://devcenter.heroku.com/articles/python-support)
- Show the latest Docker Hub URL links.

Documentation fix in CI SSH keys setup
In recent versions of Docker, the `/.dockerinit` file doesn't exist any more when running inside a container. That file is used in the example here to detect whether the runner is running inside Docker or not. Change it to check for the existence of `/.dockerenv`, which does exist in all current versions of Docker.
See merge request !3938
Replace '-n' with '--name' in docker related documentation
`-n` for `docker run` is outdated. We should use `--name` instead. This MR fixes the example in documentation.
