✨ Code completion ✨ Is there some sort of completion plugin or typing that we could possibly use to improve the DX in an IDE such as VSCode ? In any other languages, the class typings usually help with Resource parameters in Pulumi, but in YAML there's no such thing... right ? I'm using GitHub Copilot and it honestly does a decent job, but official completion would be better 😉

Yes, we have a VSCode extension in beta, but not yet published on the Visual Studio Marketplace. You can install it manually though: https://github.com/pulumi/pulumi-lsp
