Use readFileSync to load package json instead of createRequire

Using createRequire, caused problems when OneSDK was bundled for use on Vercel. This way, hopefully, it will properly resolve the URL to file and include it in the bundle.

Needs to be tested, but I don't see better way then publishing it and actually building on Vercel because bulding locally works.

Looks okay to me, although I'm very surprised readFileSync takes both paths and file URIs while readFile only takes paths.

I've checked the build output in pod and it does look like it's resolving the import to something better now (before it was generating an absolute path at build-time), although I have no idea if it's going to bundle the json file correctly or not because VeRcEl.

I think the most significant difference is not using createRequire because webpack in NextJS isn't properly handling files added this way and aren't included in the final build. My hope, is that using new URL() it will work as we need. But who knows, this still feels like dark magic.
