[Typo]: example code contradicts other `startTransition` examples

Summary

The example action code in startTransition needs another startTransition in order to handle the await per this limitation.

Details

set functions following await inside startTransition need to be wrapped in another startTransition to be handled correctly.

Current

    startTransition(async () => {
      const {error} = await updateName(name);
      // TODO: wrap `set` functions in another `startTransition`
      if (!error) {
        setError(error);
      } else {
        setName('');
      }
    })

Fixed

    startTransition(async () => {
      const {error} = await updateName(name);
      startTransition(() => {
        if (!error) {
          setError(error);
        } else {
          setName('');
        }
      })
    })

Admittedly, this may make the example less clear. As an alternative, maybe include a mention of the correct way to use await and marking subsequent state updates as Transitions.
