React Router example has missing Dockerfiles

https://github.com/vercel/examples/blob/86d230e2fc94e9e41eecccfa23bd6041f6130613/framework-boilerplates/react-router/README.md

This template includes three Dockerfiles optimized for different package managers:

Dockerfile - for npm
Dockerfile.pnpm - for pnpm
Dockerfile.bun - for bun

But there's only one Dockerfile for npm

The page on vercel also claims the same https://vercel.com/templates/react-router/react-router-boilerplate
