NavigationAgent - ending navigation early note is incorrect

[lokimckay]

Your Godot version: 4.4.1

Issue description:
NavigationAgent2D and 3D both contain this note under the target_desired_distance property:

You can make navigation end early by setting this property to a value greater than path_desired_distance (navigation will end before reaching the last waypoint).

I believe that instead of path_desired_distance the author actually meant distance_to_target().

It doesn't make sense that navigation would end if the target_desired_distance is set to a value larger than path_desired_distance but smaller than distance_to_target()
