Description
This PR fixes a flaky test in
TestDelete/Prebuilt_workspace_delete_permissions: coder/internal#764Previously, all subtests used the same context created at the top level. Since the subtests run in parallel, they could run for too long and cause the shared context to expire. This sometimes led to context deadline exceeded errors, especially during the
testutil.Eventuallycheck for running prebuilt workspaces.The fix is to create a fresh context per subtest, ensuring they are isolated and not prematurely cancelled due to other subtests' durations.
