pnpm 9.0.0-alpha.0 on Node.js NPM

Major Changes

Node.js v16 support dropped. Use at least Node.js v18.12.
Support for lockfile v5 is dropped. Use pnpm v8 to convert lockfile v5 to lockfile v6 #7470.
The dedupe-injected-deps setting is true by default.
The default value of the link-workspace-packages setting changed from true to false. This means that by default, dependencies will be linked from workspace packages only when they are specified using the workspace protocol.
Use the same directories on macOS as on Linux. Don't use directories inside ~/Library on macOS #7321.
The default value of the hoist-workspace-packages is true.
