Dockerfile should respect selected package manager

[7up-charsi]

When running pnpx create-react-router and selecting pnpm as the package manager, the Dockerfile template is hardcoded to use npm, e.g. npm ci, npm ci --omit=dev, npm run build, ["npm", "run", "start"]

Expected behavior

The Dockerfile should use the selected package manager pnpm consistently throughout, so it matches the project setup.

Steps to reproduce:

• Run pnpx create-react-router .
• Choose pnpm as the package manager
  Inspect the generated Dockerfile

Current behavior:

Dockerfile still uses npm commands.

The Dockerfile is part of a static template, the CLI to create a new app only copies the template into a folder, there's nothing special happening.

If you want a Dockerfile that uses pnpm you can fork the original template, change it to use pnpm, then upload it to GitHub and use --template user/repo to tell the CLI to use that repo as template.
