"2D lights and shadows" page should have a section about light limits

[GentlemanHal]

Your Godot version:
4.5.stable

Issue description:

Under the 3D part of the manual it talks about the limitations of lights.

However these limitations are not mentioned under the 2D part of the manual. This feels like an oversight as presumably these (or some) limitations also apply to lights in a 2D scene?

Further context
This came to my attention by a topic that was raised on the Godot Forums I think I found a Godot bug. I knew I'd read about light limitations, which made sense as I'm working on a 3D game.
