Fix the ariaLabel option on the axis mark.
Including a realistic use case where we don't want the aria-label of the custom mark to be "axis-x", otherwise Plot skips the implicit axis.

The test chart — a continuous “crosshair-x” — is not necessarily what I would recommend to use (maybe I'd anchor the new mark at the top, or I would fade out the axis mark when hovering…), but it's a nice way to see how things overlap—and consistent with what the crosshair mark does.
[Note that this is not enough to solve the continuous crosshair issue (#1629); visually OK if you add these two marks in x and y, but the Plot's value on the dispatched input event is either x or y — what we want is (x, y).]
