man: Drop "internally," which is misleading

The existing text misleads readers into thinking how the notify socket protocol is "internals" and that they can only use the functions. However, the socket is part of the Interface Stability Promise. So, we should drop "internally" from the description so the man page both indicates both how the functions work and how one would talk to the socket directly.
