Add the structuredClone method example on the Updating Objects in State page.

[paterson1720]

In addition of using the spread operator to update state objects, we can use the global structuredClone method of JavaScript to make a copy of the state, mutate the copy, and set the state with the new object.
In this PR I added a section to show an example using the structuredClone method.
