Out of Stock Component

[gvc]

I'm creating this issue to let chime in if this should be an atom/molecule or organism and if it should be implemented on faststore or on base.store.

The Out of Stock component represents the content that is shown to the user, either through a modal or on the context the user is in, so they can add their e-mail to be noticed when something comes back to stock.

Maybe organism, @faststore/ui?. I think it's an organism because that Notify Me button would be a LoadingButton, which is a molecule
