### Description

- Handle scenarios where we cannot determine package manager or
workspaces globs
- Add special handling for pnpm-workspace.yaml, since all of the other
package managers use package.json

### Testing Instructions

Added two tests, one each for pnpm and npm, to test a basic recovery
from an error state


Closes TURBO-2654
