Current Behavior

npm i runs Prepare script concurrently across all workspaces.

This causes major problems when using TypeScript and having one workspace dependent on another, since the build (prepare script) runs concurrently, there is no way to ensure the prepare command is done on one workspace before running on the next.

Expected Behavior

It to actually follow what the documentation says (https://docs.npmjs.com/cli/v7/using-npm/workspaces#running-commands-in-the-context-of-workspaces):

Nothing in there says anything about commands being run concurrently, or at the same time.

Steps To Reproduce

1. Create 2 workspaces
2. Add a prepare command to each where the second is reliant on the first completing
3. Run npm i
4. Notice that everything fails since the commands are run concurrently
