Always use device authorization in e2e t (#5106)

### Problem
- Auth now uses authorization grant flow by default but that ends up causing 2 issues in e2e tests:
    - We need to automatically press the "trust external url" popup created when we attempt to open the authorization url otherwise we get "Error: DialogService: refused to show dialog in tests. Contents: Do you want Code to open the external website?" when running the e2e tests
    - We don't support authorization grant flow in the auth lambda

### Solution
- Just use the device code auth flow until we support the auth grant flow
