Add Gift Membership Digital Pass Send Date in Sales Order Note

Currently, if you have gift membership digital pass send date enabled, the gifter can select a date to send the digital pass, but there is no way for us to see it. That means they are selecting a date for the member to receive their digital passes, but their physical packet might come at a completely different time. It should be added as a Sales Order Note just like it is when you have the feature disabled. Then we could see when they want the membership to arrive.
