Add a docker file to run the test case locally for figures.

[Anas-hameed]

Change description

Docker container files were created to run the test cases locally.

• We can use ' pdb/breakpoint` by opening the container through VS Code and do the respective development.
• Additionally, we can run each test case separately and fix the issue.

Commands:

• Build Image: docker image build -t figures-test .
• Connect the Docker image from the VS Code sidebar.

• Run Image: pytest . or we can run pytest tests/test_tasks.py to run the test cases in a specific file.

Dependencies:

Dev Container: https://code.visualstudio.com/docs/devcontainers/containers

Special thanks to @Danyal-Faheem for writing the docker file.
