Create .devcontainer

[khiron]

The .devcontainer provides an isolated docker container management within VS code

It will have to be able to pass through .ssh authentication from the host OS to the container so a user can check code into their fork of the repo from within the container without having to reauthorize.

The container will install a fresh build of;

• python 3.10
• zsh
• ohmyzsh

additionally to update the pip database and pip install -r /requirements.txt
