fix: display multiple lockfile warn if neither `outputFileTracingRoot` or `turbopack.root` option is provided (#82164) > Better to be reviewed with "Hide whitespace". This PR fixed a bug where `findRootDir()` was called and displayed multiple lockfile warnings even if the app had `turbopack.root`, as there was no `outputFileTracingRoot`. x-ref: https://github.com/vercel/next.js/pull/82164#discussion_r2240470772 Also, added information about the `outputFileTracingRoot` option and its docs to the warning, as it was omitted from https://github.com/vercel/next.js/pull/82052.
