Use neutral element as init in reduce doctest (#55065)

jakobnissen · web-flow · commit 23748ec9cc2f · 2024-07-09T15:36:47.000+02:00
The documentation of reduce states that init must be the neutral
element. However, the provided doctest uses a non-neutral element for
init. Fix this by changing the example.
