[FEATURE REQUEST] Adding a Dev Container

[PSFW]

Is your feature request related to a problem? Please describe.
I've been struggling to get this setup locally, so as I have been going I've also been crafting a Dockerfile for this.

Describe the solution you'd like
I'd like to share this Dockerfile in the form of a Dev Container, so that others are able to get this setup to run and collaborate quickly.
Dev Containers are an open standard, they are currently supported by Github Codespaces, Visual Studio Code, Visual Studio (for C++), and IntelliJ. The advantage over just sharing the Dockerfile is that a development server is automatically spun up within the container itself, so you can run and debug with the IDE as if it is running within the Container itself. What will be created is a Dockerfile and a devcontainer.json file.
I didn't want to open a random PR, I wanted to request here to see if there would be interest and if it is welcome.
