Possibility to set up 'low' and 'high' colors for gradient_color_arcadia?

[Manon-Morin]

In the gradient_color_arcadia function, when we want to create our own gradient with Arcadia colors, could it be possible to add entries such as 'low' and 'high' like this: scale_fill_gradient(low = "#3B9886", high = "#F7B846", name = "X")?
