We upgrade to version 4 and started seeing the following weird error:
```
Error: Multiple versions of pnpm specified:
Error: Error: Multiple versions of pnpm specified:
- version 9 in the GitHub Action config with the key "version"
- version yarn@1.22.22+sha512.a6b2f7906b721bba3d67d4aff083df04dad64c399707841b7acf00f6b133b7ac24255f2652fa22ae3534329dc6180534e98d17432037ff6fd140556e2bb3137e in the package.json with the key "packageManager"
Remove one of these versions to avoid version mismatch errors like ERR_PNPM_BAD_PM_VERSION
- version 9 in the GitHub Action config with the key "version"
- version yarn@1.22.22+sha512.a6b2f7906b721bba3d67d4aff083df04dad64c399707841b7acf00f6b133b7ac24255f2652fa22ae3534329dc6180534e98d17432037ff6fd140556e2bb3137e in the package.json with the key "packageManager"
```
Even though we don't specify `packageManager` in `package.json` explicitly.
Either way this change seems like an improvement to do `pnpm` version validation only if it's actually `pnpm`.
* feat: add an option to install the self-contained binary version of pnpm
* test: add a test about nodejs_bundled
* style: remove an empty line
* chore: use newer pnpm
* chore: update dependencies
* feat: rename `nodejs_bundled` to `standalone`
as @zkochan suggested
* docs: add
