Title: API docs gardening

- Don't document nbformat.current (deprecated)
- Do document nbformat.v3 and nbformat.v4 again, except for nbbase modules (which are exposed at package level)
- Use `__all__` to get names exposed from nbformat, nbformat.v3 and nbformat.v4 packages.
- Don't document `html.allow76`, as it's not public API.
