fix(ui): disable UI on all dry runs (#8269)

### Description

The UI does not make sense for dry runs. I didn't notice this since I
would usually pipe the dry run output somewhere e.g. `turbo build
--dry=json > run.json`.

### Testing Instructions

Verify that `turbo build --dry` and `turbo build --dry=json` no longer
start up the UI
