Give Merchant ability to re-trigger confirmation (and/or reminder) emails

There are some scenarios where a customer may not have received an email confirmation, or if an experience is changed from regular to e-ticketed, the customer needs the ticket email. In this case, it would be nice for the merchant to be able to trigger the confirmation email to re-send so that they can get the most up-to-date email info. Here are the known cases where it'd be helpful to be able to send out an email to the customer manually: - The customer says, "I didn't get it" because they deleted it or there was an email hiccup - The merchant changes the event type to e-Ticketed and the customer needs the ticket (edge case) - The merchant creates a Shopify draft order for an Experiences-controlled product and needs to send the confirmation. (The Experiences app doesn't currently do this automatically) Solution: Add a button/action to the list of attendees (per order) that will allow a merchant to resend the booking confirmation.
