Add a Development Container for a more seamless local experience

[tarebyte]

Hello!

While I was working on https://github.com/chaynHQ/soulmedicine/pull/305 and getting my local environment ready to go, I noticed that there were a lot of dependencies to get setup.

In order to make it easier to contribute, I thought it might be nice to have a way to run it all locally only relying on Docker and potentially VSCode if that is your editor of choice.

This Pull Request introduces a Dev Container for running the application without having to install any of the necessary dependencies on your machine. It uses the existing services defined in docker-compose.yml so that the services running are consistent.

Here's what it looks like in VSCode.

Thanks to using Ubuntu Jammy as the base image, this can support ARM and Intel based machines.

If this is a path we'd like to move forward with, I'm happy to make changes to the README to show this as an option when getting started.

Thanks!

Hey ! Thank you for this! I didn't have my notifications turned on so I didn't see this PR. This all makes sense to me. I will look through this today

No rush at all, thanks so much for taking a look!

I think this approach is great. I didn't know about dev containers so this is a great new addition. Thank you! I couldn't quite get this one working (most likely my lack of understanding) but I assume with start up instructions that I will be able to 😄

I'll update the README/documentation before merging.
