fix: update `ui` suggested value in error message for turbo.json (#10896)
### Description
Fix error message for `"interactive": true` so it correctly requires
`"ui": "tui"` in `turbo.json`.
### Testing Instructions
1. Set `"interactive": true` for a task without `"ui": "tui"` in
`turbo.json`.
2. Run a Turbo command and check the error message.
3. Verify the error message now points to `"ui": "tui"`.
