[router] Fix false positive redirect deprecation since version 2.0.1 when using Screen

[sync]

Why

WARN The redirect prop on is deprecated and will be removed. Please use router.redirect, fixes expo/router#834

I think issue is here perhaps https://github.com/expo/router/blob/f69e31c84a83ceb6d678dfb8aeed708974d301a8/packages/expo-router/src/views/Screen.tsx#L49

if you look at the code, if you do this for example:

<Stack.Screen
       options={{
         title: params.name,
       }}
     />

Then deprecated prop would end up being undefined because redirect would not be set

    useDeprecated(
      "The `redirect` prop on <Screen /> is deprecated and will be removed. Please use `router.redirect` instead",
      redirect
    );

Then looking at useDepecated code here:

export function useDeprecated(
  message: string,
  guard: unknown = true,
  key = message
) {
  return useWarnOnce(key, guard, `Expo Router: ${message}`);
}

the guard would end up being set to true because of the default value guard: unknown = true

How

Avoid sending an undefined redirect prop to the guard

Test Plan

Run updated code and make sure warning is gone
