Implementation info for constants need to be updated

[cengiz-pz]

Your Godot version:
4.2.2.stable

Issue description:
The constants section of the documentation for the Node class is as follows:

NOTIFICATION_APPLICATION_RESUMED = 2014

Notification received from the OS when the application is resumed.

Implemented only on Android.

NOTIFICATION_APPLICATION_PAUSED = 2015

Notification received from the OS when the application is paused.

Implemented only on Android.

NOTIFICATION_APPLICATION_FOCUS_IN = 2016

Notification received from the OS when the application is focused, i.e. when changing the focus from the OS desktop or a third-party application to any open window of the Godot instance.

Implemented on desktop platforms.

NOTIFICATION_APPLICATION_FOCUS_OUT = 2017

Notification received from the OS when the application is defocused, i.e. when changing the focus from any open window of the Godot instance to the OS desktop or a third-party application.

Implemented on desktop platforms.

However @ztc0611 's PR states that the above four constants are now supported on both Android and iOS.

It looks like the PR was not included in 4.2.2. Sorry, my mistake. The docs are updated for 4.3.
