Updated Admin GraphQL/Storefront ExternalVideo URL fields

As part of the 2022-04 API release, we've updated the Admin GraphQL and Storefront APIs to provide clearer URLs for the ExternalVideo type:

• The embeddedUrl field has been deprecated in favor of originUrl. Like embeddedUrl, originUrl returns the URL to the video on its hosted platform (either Vimeo or YouTube).
• A new field called embedUrl has been added. It returns the URL required to embed the video inside an iframe.
