pnpm version problem in Build Typescript

Start with the "Build Typescript" GitHub Actions workflow and package.json, comparing the pnpm version in the action configuration with the packageManager entry. Reproduce the workflow failure and make the version source consistent, then confirm that the workflow completes without the multiple-versions error.

I keep my pnpm version pretty up to date (think I have min age set to 3 days).

The "Build Typescript" doesn't like this - it seems stuck on wanting v9.

Run pnpm/action-setup@v4
  with:
    version: 9
    dest: ~/setup-pnpm
    run_install: null
    cache: false
    cache_dependency_path: pnpm-lock.yaml
    package_json_file: package.json
    standalone: false
Running self-installer...
  Error: Multiple versions of pnpm specified:
    - version 9 in the GitHub Action config with the key "version"
    - version pnpm@11.2.1 in the package.json with the key "packageManager"
  Remove one of these versions to avoid version mismatch errors like ERR_PNPM_BAD_PM_VERSION
