feat(vscode): try to resolve the rome package from the workspace root

[leops]

Summary

Fixes #3635

This PR makes use of the resolve library to resolve the corresponding @rometools/cli-* package for the current platform from each workspace root folder. This lets the extension automatically detect and use the correct version of the language server if the workspace has an explicit dependency on the rome package

Test Plan

I built and installed the extension locally, opened a test workspace with the rome package installed, and checked the extension is correctly using the version of Rome loaded from npm instead of its own bundled binary
