Turbopack: fix test case and update project_update to turbo_tasks::run too (#83978) ### What? Changing an env var that is used in an RSC doesn't lead to HMR updates. It only refetches the RSC stream and no compilation happens at all since the env var is consumed only at runtime. This test did pass before as the `run_once` created a task for the `project_update` and we counted that as computation. Changing this to `turbo_tasks::run` removes the once task and no computation happens at all.
