Need for URI and CID of author repost on app.bsky.feed.getAuthorFeed response

Is your feature request related to a problem? Please describe.

We can get uri or repost uri if calling getAuthorFeed by accessing post.viewer.repost with user auth, but there is no way to know the repost record uri from another author.

Describe the solution you'd like

the addition of "URI" and "CID" field of author repost to schema
