Installation instruction does not contain set up with Docker

[iamkuldeepsingh]

Description

Most of the developers are using python with Docker now a days and I see instructions contain only conda and pycharm. I will suggest to have the setup with Docker as well

Context

I still find it difficult to setup casualnex on local setup, however when I did with Docker it was much simpler and reproducible, hence would like to add this feature and if needed I can do that and contribute as well

Possible Implementation

We could use a base python image or a standard image loaded with other packages and extend it (if needed I can share how I did it)

Possible Alternatives

Alternatives are already available
