Version 4: Invalid prettier configuration detected when using a config from an npm package.

[Lusito]

Summary

I use .prettierrc.json to load my prettier-config from node_modules. This works in command line prettier.

When I try to use the formatter, however, it fails, telling me my prettier config is invalid.
Cannot find module '@lusito/prettier-config' from '<my-root-path>'

Github Repository to Reproduce Issue

Link to a Github repo that can be used to reproduce the issue.

Steps To Reproduce:

1. Create an NPM project
2. Install a prettier config, for example mine: @lusito/prettier-config.
3. Create a .prettierrc.json with content "@lusito/prettier-config"
4. Use prettier code-formatter => boom

Expected result

It should work just like the CLI

Actual result

An error message shows up

Additional information

VS Code Version: 1.43.2

Prettier Extension Version: 4.0.0. It works when I switch back to 3.2.0 (though trailing commas seems to be different for some reason)

OS and version: Win7
