Add examples to zoom description (#8199)

I misread this description originally as `zoom: 1` is twice as big. I think my brain skipped the "increasing" word. I added some examples to hopefully make this harder to miss.

 To render, `OrthographicView` needs to be used together with a `viewState` with the following parameters:
 
 * `target` (Number[3], optional) - The world position at the center of the viewport. Default `[0, 0, 0]`.
-* `zoom` (Number|Number[2], optional) - The zoom level of the viewport. `zoom: 0` maps one unit distance to one pixel on screen, and increasing `zoom` by `1` scales the same object to twice as large. To apply independent zoom levels to the X and Y axes, supply an array `[zoomX, zoomY]`. Default `0`.
+* `zoom` (Number|Number[2], optional) - The zoom level of the viewport. `zoom: 0` maps one unit distance to one pixel on screen, and increasing `zoom` by `1` scales the same object to twice as large. For example `zoom: 1` is 2x the original size, `zoom: 2` is 4x, `zoom: 3` is 8x etc.. To apply independent zoom levels to the X and Y axes, supply an array `[zoomX, zoomY]`. Default `0`.
 * `minZoom` (Number, optional) - The min zoom level of the viewport. Default `-Infinity`.
 * `maxZoom` (Number, optional) - The max zoom level of the viewport. Default `Infinity`.
