operator documentation "<" and ">" are missing for Vector types.

**Your Godot version:**
3.x, presumably 4.0

**Issue description:**
The operators less than and equal than is not defined in neither the Vector2 or the Vector3 class docs. This should be documented since it is ambiguous. What this operator compares is in the context of Godot is the euclidean lengths of the vectors compared. However the operator is in other context for example used to compare theta in a circular vector space or to compare the component sum.
