Demo of issue#4983 reported to turborepo

[NullVoxPopuli]

Reported turbo issue: vercel/turbo#4983

Problem: rollup's watch mode is killed by turbo, or not waited for?, hard to tell.

Reproduction steps:

1. git clone git@github.com:NullVoxPopuli/limber.git
2. cd limber
3. git checkout how-to-get-turbo-rollup-watching
4. pnpm i --ignore-scripts
5. observe that in packages/ember-repl/addon/package.json the start script is rollup --config --watch
6. try to start watch mode via turbo: pnpm turbo start --filter ember-repl
7. observe that turbo exited, when it should have not-exited due to rollup being in watch mode
8. cd packages/ember-repl/addon
9. pnpm start
10. observe that the start script in this package is a long-running watch mode that doesn't exit unless Ctrl+C is pressed (or some other kill/stop process signal is sent to the process)
