Loosen add_state_scoped_event trait bound. (#19401)

Browse Source 
Fixes #18623, allowing `add_state_scoped_event` to work with computed
states.

As a side note, should state scoped events be updated to match the
recently changed [state scoped
entities](https://github.com/bevyengine/bevy/blob/main/release-content/migration-guides/rename_StateScoped.md)?
