Expected behavior

pnpm turbo watch web#build should rebuild the web package when the external.json file changes.

Actual behavior

pnpm turbo watch web#build does not rebuild the web package when the external.json file changes.

To Reproduce

1. Run pnpm turbo watch web#build
2. Change the external.json file
3. The web package should rebuild

Additional context

At the same time pnpm turbo run web#build works as expected. It rebuilds the web package when the external.json file changes upon running the command after changing the file.
