[Feature Request] - Use components without <ShopifyProvider/>

[DavidWittness]

As I was building the guides for hydrogen 2, some of the feedback I received was that wrapping the whole app in just to use the Shop Pay button felt strange.

Snooping on the code a bit, it looks like the only code that is being pulled from the provider is the shop ID.

Describe the solution you'd like
Include 2 ways to use Shop Pay button (and other components where it makes sense).

If wrapped in a Provider, you don't need to pass in props like shop ID.
If not wrapped in a Provider, you can pass in props to the component.

Additional context
I think the overall goal is to have something copy/pasteable that works in any context.
