Collaborative Users can't share (reshare) Collaborative Photo Albums

[git529]

When a user creates a photo album, and adds collaborators, then those collaborators don’t have an option to [re]share those albums in which they are collaborators.

There should be an option to allow this.

That would be very useful. When I add a collaborator to an album, I would expect them to have the possibility to share this album to their friends, via a public link.
At the moment, I have to add a collaborator AND send them a public sharing link, as they can't create their own.

The possibilities for the collaborator to work on the album feel very limited overall. E.g. an option, if the collaborator wants to see the album in their timeline (whether in the photos-app or memories-app) would be great.
