Describe the Bug

If don't have a pnpm-workspace.yaml turbo throws this error which is miss leading:
× root task //#dev (turbo dev) looks like it invokes turbo and might cause a loop

#5290 (reply in thread)

Expected Behavior

A warning or error message: monorepo configuration for pnpm could not be found. Make sure you have setup workspaces correctly. See https://pnpm.io/workspaces

This will save users a lot of time debugging if they accidentally renamed or removed pnpm-workspace.yaml.

2. Remove the pnpm-workspace.yaml
3. Run pnpm run dev
