Subject: [PATCH] Change visibility of `bevy::core::update_frame_count` to
 `pub` (#10111)

# Objective
Closes #10107

The visibility of `bevy::core::update_frame_count` should be `pub` so it
can be used in third-party code like this:

```rust
impl Plugin for MyPlugin {
    fn build(&self, app: &mut App) {
        app.add_systems(Last, use_frame_count.before(bevy::core::update_frame_count));
    }
}
```

## Solution
Make `bevy::core::update_frame_count` public.

---

## Changelog

### Added
- Documentation for `bevy::core::update_frame_count`

### Changed
- Visibility of `bevy::core::update_frame_count` is now `pub`
