Fix T93899: Incorrect decorator buttons for geometry nodes vector/colors

For properties exposed to the geometry nodes modifier, decorators didn't
work at all for colors and it only worked on the X component of vectors.
The fix is to use -1 for the RNA index of the decorator button instead
of 1, which lets the UI code figure out what to do with arrays.
