feat: support bare specifier resolution with package.json (#17864)
This commit enables resolution of "bare specifiers" (eg. "import express from 'express';") if a "package.json" file is discovered. It's a step towards being able to run projects authored for Node.js without any changes. With this commit we are able to successfully run Vite projects without any changes to the user code. --------- Co-authored-by: David Sherret <dsherret@gmail.com>
