Make note of 16 probe limit

Godot by default has a limit of 16 reflection probes in a scene. this can be increased by increasing atlas subdiv. For 3.2 and possibly 4.0. This also fixes a spelling mistake

 		The [ReflectionProbe] is used to create high-quality reflections at the cost of performance. It can be combined with [GIProbe]s and Screen Space Reflections to achieve high quality reflections. [ReflectionProbe]s render all objects within their [member cull_mask], so updating them can be quite expensive. It is best to update them once with the important static objects and then leave them.
+		Note: By default Godot will only render 16 reflection probes. If you need more, increase the number of atlas subdivisions. This setting can be found in [member ProjectSettings.rendering/quality/reflections/atlas_subdiv].
