Change WinitPlugin defaults to limit game update rate when window is not visible (for real this time)

[maniwani]

Objective

I goofed. #7611 forgot to change the default update modes set by the WinitPlugin.

bevy/crates/bevy_winit/src/winit_config.rs

Lines 53 to 60 in ce5bae5

	impl Default for WinitSettings {
	fn default() -> Self {
	WinitSettings {
	focused_mode: UpdateMode::Continuous,
	unfocused_mode: UpdateMode::Continuous,
	}
	}
	}

bevy/crates/bevy_winit/src/lib.rs

Line 127 in ce5bae5

.init_resource::<WinitSettings>()

Solution

Change Default impl for WinitSettings to return the game settings that limit FPS when the app runs in the background.

I would really prefer if we fix issues #11273 and #11274 before merging this as this would create a lot of issues for CI (https://github.com/bevyengine/bevy/actions/runs/7493996227/job/20400936658 would have timed out)
