Publish misc. Turbopack packages

The `turbopack/` directory includes miscellaneous JavaScript packages that should be published to npm. This was handled in https://github.com/vercel/turbo/tree/5fc75a38477e9f810bc4ee8aba4c741425fe2342 before Turbopack moved to the Next.js repo.

Test Plan: Run workflow manually or with this PR and verify the publish xtask is run.
