Get a thread subscription for the authenticated user
GET {{baseUrl}}/notifications/threads/:thread_id/subscription
This checks to see if the current user is subscribed to a thread. You can also get a repository subscription.
Note that subscriptions are only generated if a user is participating in a conversation--for example, they've replied to the thread, were @mentioned, or manually subscribe to a thread.
