fix(adapters/next): wrap setOptimisticSearchParams in startTransition

[aryasaatvik]

on next 15 app router. I was getting an error when updating a search param in a form input event handler. wrapping setOptimisticSearchParams with startTransition fixed it

<Input
  placeholder="https://example.com/font.woff2"
  {...field}
  onChange={(e) => {
    setWebFontUrl(e.target.value);
    field.onChange(e);
  }}
/>

error

ConsoleError: An optimistic state update occurred outside a transition or action. To fix, move the update to an action, or wrap with startTransition.
