Mark canvasContext as optional

Browse Source 
In #20016, the `canvasContext` property of `RenderParameters` was deprecated in favor of the new `canvas` property.

The JSDoc was updated to include the new parameter along with the old one.

I think the old one should be enclosed in `[]` to mark it as optional (and to allow usage from TypeScript with just the `canvas` parameter provided).

I also reordered the properties so that all required properties come first, follow by optional ones.
