Fix some missing instance domains. Update Sync link action for beta 30.

Deep linking proxy for Mastodon on Android, allowing you to launch your selected client automatically. A simple app for automatically launching fediverse links in your preferred Mastodon client. Unfortunately, most Mastodon clients don't have a way for Mastodon Redirect to interface with them. Mastodon redirect relies on clients having a link sharing target that can parse and open fediverse links. Clients such as Tusky and Trunks do have share targets, but they can only be used to create new posts, with the shared link as the content. Other clients have no share targets at all.
