Set your default directory in VS Code's open dialog

This is my workflow for opening a project in VS Code:

1. Open an empty window of VS Code
2. Hit cmd+O
3. Navigate to my `~/Documents/...` directory
4. Hit enter

In my opinion, that's a few too many steps. I've made it a little better by changing the `files.dialog.defaultPath` setting (added almost exactly one year ago).

Hope this helps.
