chore: Add vscode upstream as a gitsubmodule
Issue: #34 (closed)
What does this MR do?
It adds https://github.com/microsoft/vscode/ as a submodule of this VSCode Fork project. This will allow us to use a patch strategy to manage upstream changes and apply customizations. You can read more about the patch strategy in #32 (closed).
