chore: Add dev container infrastructure

[ianjmacintosh]

Because

I wanted to contribute to this project but setup took me a while. These changes will help other engineers get up and running with a remote dev environment running this project dramatically faster than manually going through the local setup process.

Using GitHub Codespaces' free tier, I can push a button directly within the GitHub web UI and have a brand new isolated environment running The Odin Project in about 5 minutes

This PR

• Adds development container files to easily create environments running The Odin Project website

Additional Information

Although I mention GitHub Codespaces because it's what I personally use, other organizations like CodeSandbox and DevPod also support dev containers, I'm just much less familiar with them.

To try it out yourself, pull this branch to your fork, navigate to it in the GitHub UI, and from the "Code" dropdown choose "+" to create a new workspace:

After your codespace is up and running, type bin/dev in your terminal to start your web server. VS Code Web will open a dialog window telling you how to connect in your web browser. The URL will look something like:

Hey @ianjmacintosh, we appreciate you taking the time to do this. But we talked it over within the team, and it isn't something we'd be willing to maintain at the moment.
