Yarn PnP SDK shows several "@yarnpkg/pnpify" errors

Summary

I use the Yarn PnP version of the “SDK” (.yarn/sdks/prettier/index.js) and am getting several of these errors when loading Prettier in VSCode:

Your application tried to access @yarnpkg/pnpify, but it isn’t declared in your dependencies; this makes the require call ambiguous and unsound.

Steps To Reproduce:

1. Install Yarn PnP SDKs: dlx @yarnpkg/pnpify --sdk vscode
2. Use this in settings.json: "prettier.prettierPath": ".yarn/sdks/prettier/index.js"
3. Load VSCode

Expected result

Everything starts cleanly.

Actual result

The Output panel contains this:

Formatting seems to work but the Output panel is full of these errors.

This is expected, the sdk uses @yarnpkg/pnpify to allow prettier to scan node_modules for plugins, you need to add @yarnpkg/pnpify to your dependencies or remove that part of the sdk if you don’t need it

I have confirmed in https://github.com/borekb/prettier-vscode-1844/pull/1, thanks a lot @merceyz!
