doc: fix incorrect test runner mock examples

The CJS mock.timers.setTime example asserted the timer ran right after
setTime() with no tick() call, which contradicts the documented behavior
and the ESM example above it. The mock.module example called .fn() on an
export named foo. Both threw if run.
