[Feature Request]: Create development docker container

[ConnorYoh]

Feature Description

Create a development docker container to work with VS code. Developers can use the dev container to start contributing to Stirling-pdf without installing any dependencies other than docker and VScode

Why is this feature valuable?

Reduce time and effort barrier to contribute to the project as contributors will not need to install native dependencies and can work within a predefined container.

Suggested Implementation

• Use VS code to generate a dev container with base image as per latest dockerfile
• Edit generated dockerfile to install dependencies as per the latest Dockerfile (not ultra-lite or fat)
• Add environment variables needed test effectively
• Ensure any configurable environmental variables can be changed easily from within a running dev container.
• Multiple RUN commands to enable caching of build
