Forking a folder of foreign data lake creates multiple copies of notebooks

[sanketd11]

• Load any notebook that belongs to a folder from foreign data lake
• Fork the that folder multiple times

As per the current behavior, Notebook folder belonging to other user can be forked only once. But in this scenario, we are able to fork that folder multiple times. Also instead of creating multiple folders , it creates multiple copies of notebook with same name in the same folder

The "forked only once" behavior is not desired behavior: it's just a limitation forced on us by GitHub.

Currently the notebook numbering behavior is implemented client-side, and only for cases where we are copying instead of truly forking. If we want to support numbering for these cases, we'll have to reimplement it server-side (which is kind of a PITA because the server doesn't know anything about the notebook tree).
