Add vscode.dev

[milkmuffin]

vscode.dev is a quick way to get a lot of the functionality of VS Code running in the web. It allows you to work from a local folder, or a remote repository.

It seems like a stripped down version of GitHub Codespaces.

Also, it seems like it doesn't allow executing code or debugging code, it only allows you to author code.

So probably wouldn't fit in the IDE category but maybe snippet category.
