Use pnpm with Volta for Node.js testing

- Add nodeModulesDir: "none" to deno.json to prevent Deno from
  using node_modules when package.json is present
- Add pnpm-workspace.yaml for pnpm workspace configuration
- Add package.json with Volta pinned versions and packageManager field
- Update bdd/package.json to use workspace:* for local deps
- Update CI to use pnpm/action-setup and actions/setup-node
- Update README with Volta installation instructions

 ### Node.js Testing
 
-Packages with Node.js support have a `package.json` with a `test` script. To run
-all Node.js tests across all packages:
+This repository uses [Volta](https://volta.sh/) to manage Node.js and pnpm
+versions. The versions are pinned in `package.json`.
+
+#### Prerequisites
+
+Install Volta if you haven't already:
 
 ```bash
-npm install
-npm test
+curl https://get.volta.sh | bash
 ```
 
-This runs `npm test --workspaces --if-present`, which executes the `test` script
-in each package that has one defined.
+Volta will automatically install the correct Node.js and pnpm versions when you
+run commands in this repository.
+
+#### Running tests
+
+```bash
+pnpm install
+pnpm test
+```
 
 #### Adding Node.js support to a package
