Add .devcontainer configuration for Python development

[dosine-staging]

This pull request introduces a new .devcontainer folder containing the necessary configuration files to set up a development environment using Docker.

Changes Made:

• Dockerfile: A Dockerfile has been added to define the development container. It is based on the Python 3.10 image and includes options to install Node.js, GitHub CLI, and upgrade pip packages. The Dockerfile also installs essential tools and cleans up unnecessary files to optimize the image size.
• devcontainer.json: This file has been created to configure the development container settings, specifying the Dockerfile to use and other build arguments.

These changes will allow developers to easily spin up a consistent development environment tailored for Python projects.
