Prevent last_trigger_id from overflowing

[OwlyCode]

Objective

This prevents overflowing the last_trigger_id property that leads to a panic in debug mode.

panicked at C:\XXX\.cargo\registry\src\index.crates.io-6f17d22bba15001f\bevy_ecs-0.15.2\src\world\unsafe_world_cell.rs:630:18:
attempt to add with overflow
Encountered a panic when applying buffers for system `bevy_sprite::calculate_bounds_2d`!
Encountered a panic in system `bevy_ecs::schedule::executor::apply_deferred`!

Solution

As this value is only used for detecting a change, we can wrap when it reaches max value.

Testing

This can be verified by running cargo run --example observers
