CanvasItem Range shows Float type when actually Double

**Your Godot Version:** 4.2.0

**Issue Description:** Documentation for the Range class shows that the value of the range is the type Float. The definition of the Range class doesn't use any Float values. Instead, it uses Double.

It also shows a Float in the Editor's Node Signal Panel, and in the downloaded documentation.
