[Fizz] Pass task.childIndex in retryReplayTask (#27594)

This was missed that we track the child index on the task. The
equivalent in retryRenderTask already has this.

The effect is that a lazy node that suspends gets its child index reset
to -1 even though it should resume in the index it left off.
