Make initial StateTransition run before PreStartup (#14208)
# Objective

- Fixes #14206 

## Solution

- Run initial `StateTransition` as a startup schedule before
`PreStartup`, instead of running it inside `Startup` as an exclusive
system.

## Testing

Reproduction now works correctly:

```rs
use bevy::prelude::*;

#[derive(Debug, Clone, Copy, Default, Eq, PartialEq, Hash, States)]
enum AppState {
    #[default]
    Menu,
    InGame,
}

fn main() {
    App::new()
        .add_plugins(DefaultPlugins)
        .init_state::<AppState>()
        .add_systems(Startup, setup)
        .add_systems(OnEnter(AppState::Menu), enter_menu_state)
        .run();
}

fn setup(mut next_state: ResMut<NextState<AppState>>) {
    next_state.set(AppState::Menu);
}

fn enter_menu_state() {
    println!("Entered menu state");
}
```
