DOC: expand "using a Docker container" section

Documentation problem

Someone unfamiliar with Docker would be confused reading this.

Suggested fix for documentation

The expansion needed is quite small, just:

1. link to the Docker installation instructions
2. link to how to develop in a container using PyCharm (current docs only link to vs code instructions)
3. mention that you might still need to rebuild the C extensions if/when you merge with upstream/master with

   python setup.py build_ext --inplace -j 4

I was able to find links for the docker installation and developing in a container using PyCharm. However, I notice this feature is only for PyCharm Professional. Is it still worth including this link? I can just mention that Professional is required?
