Move E2E tests to larger machines to see if flakyness decreases (#46960)

Summary:
This change move E2E tests to larger mac machines to see if we can reduce the flakyness.
Most of the time the flakyness is due to slowness in connecting to the simulator or slowness in Metro to provide the bundle to RNTester when we run the tests in Debug.
More power should speed-up those processes.

E2E tests took < 30 min in this diff
on Main, they took > 120 min
