Merge branch 'update-doc-ci-examples' into 'master'

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.
