Update devcontainer config

[eitsupi]

Addresses #251, replaces #252

Modify the following aspects of the previous container:

• Only had the root user in the container, causing permission issues when run locally.
• The version of Quarto CLI was hard coded and the new version could not be installed without updating the file.
• Arm64 support lacks.
• Dockerfile had to be included in the repository.

Thanks for this PR! I opened in codespaces and it seems to work great!

I'm not too familiar with devcontainers. Any chance you might be able to weigh in on these pieces from the siuba workshop config?

• "waitfor": "onCreateCommand": does this seem worth adding? It looks like it might not work in codespaces, but I guess will work when people create the devcontainer locally?
• installing the jupyter extension: I was able to get the "Run Code" button to appear in qmds after installing this. Do you mind adding? :)

Thanks again! I'm also happy to take from here / merge if useful!

I think it is the same as the default value.

I think it is worth adding. Feel free to add this PR.

Added--Thanks again for your help!

This is included in the base image, so not needed here.

The top level vscode field is the old syntax (I think this is not included in the Devcontainer spec).
