Try loading extension into cs233's vscode workspace

[yufengwng]

Once the extension is in a better state, let's try putting our extension into our vscode workspace docker image and try it out on PrairieLearn. We mainly want to confirm that the extension can be loaded, can open vcd files, and there's no networking issues. PrairieLearn's live server environment is slightly different from PrairieLearn local development, so we'll want to test on live server. We'll need to wait for #14 at the very least, since networking for docker containers on live server is disabled.

• Package our extension into an extension bundle (aka a .vsix file)
• Navigate to our pl-cs233 repo, into workspaces/vscode-wave
• Build a custom docker image that has our extension installed (you'll need to edit the scripts there)
• Push custom docker image to a new temporary "repo" on Docker Hub
• Update an example question to use this new docker image (e.g. maybe the html-example question)
• Test functionality on the live server

Coordinate with Prof. Herman throughout this process.
