Added devcontainer.json and fixed Dockerfile

[niemasd]

With this devcontainer file, VS Code (and GitHub Codespaces) will be able to create the development environment automatically. I also fixed the yarn installation in the Dockerfile.

Actually, there are some more fixes that need to be made to the Dockerfile, so don't merge this specific PR yet. The tn93 and hivtrace ones should be good to go, though

I've ported the Dockerfile to use Oracle Linux instead of Ubuntu, and I'm now stuck at the same place as I was in Ubuntu:

#118 (comment)

@stevenweaver Thoughts?

[stevenweaver]

I've updated the supported engines to 18 and 19 until underlying dependencies can be updated to support Node 20 and above in earnest.

[niemasd]

@stevenweaver Great, thanks for the info! Switching to Node 18 worked perfectly. As of the following commit:

65db705

I'm able to build directly from the development environment with the following:

yarn
yarn develop # or yarn build

So this one should be good to go now! In GitHub Codespaces, I'm even able to load the deployed web app

Many thanks @niemasd.
